To provide an electrode board for a dye-sensitized solar cell capable of obtaining a dye-sensitized solar cell with degradation with time passage of performance restrained, even when a transparent resin film with a comparatively high oxygen transmittance is used as a base material.

In manufacturing an electrode board 20 for a dye-sensitized solar cell provided with a transparent resin film 1, a transparent conductive film formed on one face of the transparent resin film, a porous semiconductor layer formed on the transparent conductive film with the use of a large number of semiconductor fine particles, and dyes supported on the surface of the semiconductor fine particles forming the porous semiconductor layer, a gas barrier layer is provided between the transparent resin film and the transparent conductive film.
