An object is to provide a highly practical photoelectric conversion element having high conversion efficiency and excellent stability using an inexpensive organic dye. The photoelectric conversion element uses oxide semiconductor fine particles sensitized by a methine dye represented by the general formula (1). (Wherein A1 and A2 are each H, a substituent, X is O, S, Se, etc., Y is an aromatic hydrocarbon residue or an organic complex residue, R1 is an aliphatic hydrocarbon residue, an aromatic A group hydrocarbon residue, a hetero residue, H, R2 is H or a substituent, R3 is a carboxyl group, an alkoxycarbonyl group, etc., n is an integer of 1 to 4, m is 0, 1/2, 1 And Z represents an ion) [Selection diagram] None |
