A dye-sensitized solar cell which sequentially comprises a photoelectrode, an electrolyte layer and a counter electrode in this order. The photoelectrode comprises a supporting body and a carbon nanotube layer (1) that is formed on the supporting body and serves as a conductive film. Meanwhile, the counter electrode comprises a supporting body and a carbon nanotube layer (2) that is formed on the supporting body and serves as a catalyst layer, said carbon nanotube layer (2) being able to serve also as a conductive film. The carbon nanotube layers (1, 2) respectively use carbon nanotubes having an average diameter (Av) and a standard deviation (&sgr;) of diameter that satisfy the relational expression 0.60 > 3&sgr;/Av > 0.20. |
