PROBLEM TO BE SOLVED: To provide a thin-film photoelectric conversion device which is flexible in manufacturing process and kept high in long term reliability in outdoor use. SOLUTION: A thin-film photoelectric conversion device comprises a front transparent electrode layer 2, non-single crystal silicon photoelectric conversion layers 3 to 5, and a back metal electrode layer 7 which are successively laminated on a transparent board 1. Furthermore a back electrode protective layer 8 is laminated on the back metal electrode layer 7, wherein the protective layer 8 is formed of a metal, which produces a passivation film high in environmental resistance or an oxide which is high in environmental resistance.
