Dye-sensitized solar cell

A dye-sensitized solar cell comprising:

• a transparent substrate;
• a conductive substrate serving as a cathode electrode;
• a porous semiconductor layer containing a dye adsorbed thereto and arranged between the transparent substrate and the conductive substrate in vicinity to or contact with the transparent substrate;
• and
• a conductive metal layer arranged in contact with a side of the porous semiconductor layer opposite to the transparent substrate and serving as an anode electrode,
• the dye-sensitized solar cell containing an electrolyte sealed therein, wherein the conductive metal layer is formed of a metallic porous body sheet having through-holes, a multitude of holes of the metallic porous body sheet are isotropically communicated with one another, and the metallic porous body sheet has a specific surface area of 0.1 m2/g or larger, a porosity of 30 to 60 vol. %, and a pore diameter of 1 μm to 40 μm.
