To provide a dye-sensitized solar cell which can be produced by a relatively easy and simple process and ensures high conversion efficiency even in cases where the thickness of the porous semiconductor layer is increased. n Dye-sensitized solar cell 10 includes, in the interior of or on the conductive-substrate-side surface of porous semiconductor layer 16, conductive metal film 20, such as a film of tungsten, having a large number of randomly located penetrations 24. Penetrations 24 of conductive metal film 20 are formed by forming a fine-particle layer on the surface of the porous semiconductor layer, forming a conductive metal film on the surface of the fine-particle layer, and making the fine-particle layer disappear by heating or solvent-cleaning. |
