The glass sheet production method of the present invention is a method for producing a surface-modified glass sheet, including a gas contact step of bringing hydrogen fluoride (HF) gas, hydrogen chloride (HCl) gas, and water vapor into contact with at least one principal surface of a glass sheet. A gas containing the hydrogen fluoride (HF) gas is used in the gas contact step, and in the gas containing the hydrogen fluoride (HF) gas, a volume ratio of the water vapor to the hydrogen fluoride (HF) gas (volume of water vapor / volume of HF gas) is 8 or more.

Provided is a terminal structure body that is to be electrically connected to a conductive body arranged on a glass for a vehicle. The terminal structure body includes: a first connection portion that is to be soldered to the conductive body and is to be electrically connected to the conductive body via solder; a second connection portion that is directly or indirectly fixed to the first connection portion and is to be adhered to at least one of the glass and the conductive body with adhesive; and a thermal shielding portion that is provided between the first connection portion and the second connection portion and is for preventing heat at a time of melting the solder from being transmitted from the first connection portion to the second connection portion. The solder is lead-free solder.


[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.
