A solar cell covered with a transparent plate through a predetermined gap includes a flexible power generating layer which photoelectrically converts light incident thereon through the transparent plate, a resin layer covering a light receiving surface of the power generating layer, and an adhesion preventing layer covering the surface of the resin layer and facing the transparent plate through the gap. The adhesion preventing layer is made of an inorganic material and has a surface roughness Sz of 1 nm or more and 500 nm or less. Thus, the outermost surface of the solar cell is constituted by the adhesion preventing layer, so that no tack mark occurs even when partial contact occurs between the solar cell and the transparent plate which face each other through the gap. As a result, it is possible to prevent deterioration in appearance due to the tack mark.
