ELECTRODE SUBSTRATE AND PHOTOELECTRIC TRANSFORMATION DEVICE

An electrode substrate of a photoelectric transformation device includes a transparent conductive substrate, a current-collecting electrode disposed on the transparent conductive substrate, and a coating film coating the surface of the current-collecting electrode. The coating film includes a combustion product of a glass paste composition applied on the current-collecting electrode. The glass paste composition includes a filler made of a material that does not melt at a temperature which is not higher than a glass transition temperature or a phase transition temperature of the transparent conductive substrate.
