Disclosed is a polymeric compound that exhibits high short-circuit current density and high photoelectric conversion efficiency when used in an organic layer contained in a photoelectric conversion element. Specifically disclosed is a polymeric compound that has a structural unit represented by formula (1). [In the formula, Ar1 and Ar2 independently represent a trivalent heterocyclic group; X1 represents -O-, -S-, -C(=O)-, -S(=O)-, -SO2-, -Si(R3)(R4)-, -N(R5)-, -B(R6)-, -P(R7)- or -P(=O)(R8)-; and R51 represents an alkyl group having 6 or more carbon atoms, an alkyloxy group having 6 or more carbon atoms, an alkylthio group having 6 or more carbon atoms, an aryl group having 6 or more carbon atoms, an aryloxy group having 6 or more carbon atoms, an arylthio group having 6 or more carbon atoms, an arylalkyl group having 7 or more carbon atoms, an arylalkyloxy group having 7 or more carbon atoms, an arylalkylthio group having 7 or more carbon atoms, an acyl group having 6 or more carbon atoms, or an acyloxy group having 6 or more carbon atoms.] |
