A windshield according to the present invention is a windshield to which an information acquisition device that emits and/or receives light to acquire information from an outside of a vehicle can be attached, and that includes a glass sheet, and a mask layer that is formed on the glass sheet and blocks a visual field from the outside of the vehicle, and at least one opening is formed in the mask layer. The glass sheet and the mask layer have different heat shrinkage percentages and are molded together by being heated. The information acquisition device is configured to be capable of using the information while reducing an influence of distortion that occurs in a predetermined range from an inner peripheral edge of the opening toward a center of the opening due to the molding.

A vehicle window glass according to the present invention includes a glass plate, a first feeding portion disposed on the glass plate, and a composite antenna element that is disposed on the glass plate and extends from the first feeding portion, wherein the composite antenna element includes a first media element that mainly receives a frequency band of first media, and a second media element that mainly receives a frequency band of second media having a higher frequency band than the first media.


A low-reflection coating of the present invention is a porous film including fine silica particles being solid and spherical and having an average particle diameter of 80 to 150 nm; and a binder containing silica as a main component, the fine silica particles being bound together by the binder. The binder further contains an aluminum compound. The low-reflection coating contains, as components, 55 to 70 mass% of the fine silica particles, 25 to 40 mass% of the silica of the binder, and 2 to 7 mass% of the aluminum compound in terms of Al_(2)O_(3). The low-reflection coating has a thickness of 80 to 800 nm. The low-reflection coating yields a transmittance gain of 2.5% or more when provided on the substrate. The transmittance gain represents an increase in average transmittance of the substrate provided with the low-reflection coating relative to the substrate not provided with the low-reflection coating, the average transmittance being measured in the wavelength range of 380 to 850 nm.

To provide a spacer member for a vacuum double glazing glass panel capable of stably maintaining a void of the glass panel and of suppressing a heat flow between the spacer member and glass sheets. The spacer member 3 being disposed at each of support points set at predetermined intervals on opposing faces of a pair of glass sheets opposing to each other when a gap formed between the pair of glass sheets is maintained under a depressurized state, wherein the spacer member 3 includes: at least one contacting member 7 having a first planar part 7A on one side and a second planar part on the other side coming into contact with the respective opposing faces of the glass sheets, and a projecting piece 8 extending integrally from the contacting member 7 for determining a posture of the contacting member 7 when the contacting member 7 is provided between the pair of glass sheets, and on the assumption that an imaginary column P that circumscribes the spacer member 3 with its height direction being vertical to the first planar part 7A is provided, the total area S1 of the first planar part 7A or the total area of the second planar part is equal to or smaller than one half of a circular cross section S of the column P.


[Problem] To provide a reinforcement for a proton conductive membrane, which can improve the acid resistance and dimension stability. [Means for Resolution] A reinforcement which is formed from a glass fiber nonwoven fabric for use in a proton conductive membrane having an arylene group, wherein the reinforcement uses a resin binder containing an arylene group as a binding component for glass fibers constituting the glass fiber nonwoven fabric.


The present invention provides a glass article including a photocatalyst film 1 containing silicon oxide particles 6 and titanium oxide particles 5, and a glass sheet 2. Assuming that the photocatalyst film 1 has a film thickness T, 80% or more of the titanium oxide particles are localized in a region between a surface of the glass sheet 2 and a position spaced from the surface by 0.6 T toward a surface of the photocatalyst film 1 in a thickness direction of the photocatalyst film 1. The glass article has an increased transmittance provided by enhancing the reflection-reducing function of the photocatalyst film 1 while maintaining the film strength and photocatalytic function of the photocatalyst film 1.
