A photovoltaic device in which, by optimizing the structures for a substrate-side transparent electrode layer, an intermediate layer, and a back electrode layer, the extracted electrical current can be increased. The photovoltaic device includes at least a transparent electrode layer, a photovoltaic layer and a back electrode layer provided on a substrate, wherein the surface of the transparent electrode layer on which the photovoltaic layer is disposed includes a textured structure composed of ridges and a fine micro-texture provided on the surface of the ridges, the pitch of the textured structure is not less than 1.2 μm and not more than 1.6 μm, the height of the ridges is not less than 0.2 μm and not more than 0.8 μm, the pitch between peaks in the fine micro-texture is not less than 0.05 μm and not more than 0.14 μm, and the height of peaks is not less than 0.02 μm and not more than 0.1 μm.
