The present invention provides a polymer compound in which a short circuit current density and a photoelectric conversion efficiency are increased when used in an organic layer included in a photoelectric conversion element. Specifically, the present invention provides a polymer compound having a structural unit represented by formula (1). [Wherein, Ar 1 and Ar 2 are the same or different and represent a trivalent heterocyclic group. X 1 is -O-, -S-, -C (= O)-, -S (= O)-, -SO 2- , -Si (R 3 ) (R 4 )-, -N (R 5 ) -, -B (R 6 )-, -P (R 7 )-or -P (= 0) (R 8 )-. R 51 is an alkyl group of 6 or more carbon atoms, an alkyloxy group of 6 or more carbon atoms, an alkylthio group of 6 or more carbon atoms, an aryl group of 6 or more carbon atoms, an aryloxy group of 6 or more carbon atoms, or 6 or more carbon atoms An arylthio group, 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. ] |
