A dye-sensitized solar cell element includes at least one dye-sensitized solar cell. The dye-sensitized solar cell includes a first base material having a transparent substrate, a second base material facing the first base material, an oxide semiconductor layer provided between the first base material and the second base material, and a sealing portion connecting the first base material and the second base material. One transparent substrate is provided for the at least one dye-sensitized solar cell, and a coating layer capable of covering a light receiving surface, which is opposite to the second base material, of the transparent substrate and transmitting light is provided on the first base material. The coating layer includes an annular peripheral portion, and a center portion provided at the inner side of the peripheral portion. An average thickness of the peripheral portion is smaller than a maximum thickness of the center portion, and the coating layer has a refractive index higher than a refractive index of the transparent substrate. |
