Providing a dye-sensitized solar cell having high durability and thermal resistance, and preventing elution of a platinum group catalyst from a catalytic electrode: by surface-treating the catalytic electrode with (a) a specific sulfur material having a molecular weight of 32 to 10,000 containing a sulfur atom having an oxidation number of &#x2212;2 to 0, (b) another specific sulfur material containing no sulfur atom having an oxidation number of &#x2212;2 to 0, but containing a sulfur atom having an oxidation number of +1 to +4 [with the proviso that the sulfur material (b) is such a material that a surface of the surface-treated catalyst electrode has a photoelectron peak within a binding energy range of 161 to 165 eV in an X-ray photoelectron spectrum], or (c) a mixture of the sulfur materials (a) and (b); and/or by adding the sulfur material into the electrolyte layer.
