Photoelectrode substrate of dye sensitizing solar battery, and method for producing same

There is provided a photoelectrode substrate of a dye sensitizing solar battery capable of preventing an electrolytic solution from directly contacting a transparent electrode film and of preventing a leak current from being produced, and a method for producing the same. The dye sensitizing solar battery 1 is formed by filling an electrolytic solution 4 in a space between a photoelectrode substrate 2 and a counter electrode substrate 3. The photoelectrodesubstrate 2 has a transparent electrode film 6 formed on the surface 5a of a substrate member 5, a titanium oxide film 7 formed by anodizing a titanium film which is formed on the transparent electrode film 6, a porous semiconductor electrode film 8 formed on the titanium oxide film 7, and a sensitizing dye absorbed and carried on the porous semiconductor electrode film 8.
