Provided is a hole-blocking layer which has excellent basic characteristics such as high photoelectric conversion efficiency, while exhibiting excellent productivity. The hole-blocking layer is produced by a process that has a step of bringing an aqueous solution containing hydrogen peroxide and titanium (IV) oxysulfate into contact with the surface of a member on which the hole-blocking layer is to be formed, and holding the contact between the aqueous solution and the member at 50 to 120C, so that an amorphous titanium oxide precursor precipitates on the surface of the member; and a step of drying the amorphous titanium oxide precursor that has precipitated on the member.

Provided are a gas sensor, which is extremely compact to be arranged for separated gas piping in semiconductor device manufacturing equipment, a gas measuring system using such gas sensor, and a gas detection module for the gas measuring system. The gas sensor is provided with a gas detection device containing a dielectric semiconductor, the electric conductivity of the gas detection device varying in response to the degree of adsorption of gases to the gas detection device, a capacitive element connected in series to the gas detection device, and a pair of electrodes which are connected to electric terminals of an electric element comprising the gas detection device and the capacitive element, wherein the gas sensor is capable of detecting the degree of adsorption of gases to the gas detection device from an electrical response changing in response to a voltage which is applied to the pair of electrodes and which periodically varies and reverses in polarity.


A production method of a hole blocking layer is provided which is applicable even to a case where the base material comprises a resin-based material, while having excellent basic characteristics, such as high photoelectric conversion efficiency. This method comprises: a liquid layer forming step that causes a liquid composition and a surface of a member on which the hole blocking layer is to be formed, to contact with each other thereby forming a liquid layer comprising the liquid composition on the surface of the member on which the hole blocking layer is to be formed, the liquid composition containing a zinc source comprising bis(acetylacetonato)zinc, a complexing agent comprising acetylacetone, and a polar solvent; and a drying step that heats the liquid layer formed by the liquid layer forming step to vaporize the complexing agent and the polar solvent from the liquid layer thereby forming a hole blocking layer comprising zinc oxide on the surface of the member on which the hole blocking layer is to be formed.

A light-emitting element used for display devices and illuminating devices has been formed on a flat substrate, and therefore, when the size of such devices is increased, manufacturing apparatuses also have to be enlarged. Also, a problem involved has been that even a failure of one light-emitting element causes the entire device to fail, making improvement of production yield difficult. To solve the above problems, in the present invention, light-emitting elements are formed as linear elements, and the linear elements are combined to form a plane light-emitting device. This enables the light-emitting device to be produced by selecting only linear light-emitting elements of good quality, and enlargement of apparatuses and enhancement of production yield can be expected.

A transparent piezoelectric sheet-with-a-frame includes a transparent piezoelectric sheet and a frame covering a peripheral edge portion of the transparent piezoelectric sheet. The transparent piezoelectric sheet includes one transparent piezoelectric film including an organic polymer, one first transparent plate electrode placed on a first main surface of the transparent piezoelectric film and having a first transparent plate electrode portion, and one second transparent plate electrode placed on a second main surface of the transparent piezoelectric film and having a second transparent plate electrode portion. An outline of the second transparent plate electrode portion is positioned inside an outline of the first transparent plate electrode portion as seen in a plan view. The outline of the first transparent plate electrode portion completely coincides with the frame, and the outline of the second transparent plate electrode portion does not at all coincide with the frame as seen in the plan view.


A transparent piezoelectric sheet includes a quadrilateral-shaped transparent piezoelectric film and a first transparent plate electrode. The quadrilateral-shaped transparent piezoelectric film includes an organic polymer. The quadrilateral-shaped transparent piezoelectric film has entire main surfaces that are piezoelectric. The first transparent plate electrode is layered on part of a first main surface of the main surfaces of the transparent piezoelectric film. One to three sides of the four sides of the quadrilateral shape of the transparent piezoelectric film and area(s) of the first main surface adjacent thereto are not covered by the first transparent plate electrode.
