## Abstract

In order to obtain a composite glass plate which shields infrared light and/or ultraviolet light, two glass substrates on which transparent conductive layers are formed respectively are disposed with the transparent conductive layers thereof facing each other. Infrared light is shielded and electric power is generated by using one glass substrate as a light incident side electrode, disposing a silicon dioxide particle layer thereon, and filling a colorless electrolyte between the two glass substrates. Further, ultraviolet light is also shielded by disposing a titanium dioxide layer on the other glass substrate. This composite glass plate is used as a window glass plate to shield only infrared light and/or ultraviolet light and transmit only visible light.
