To provide noble organic materials enabling open-circuit voltage to be further improved as compared with conventional p-type semiconductor materials.
There are provided an alternating copolymerization polymer containing a repeating unit represented by general formula (I), and an organic photoelectric conversion element containing a photoelectric conversion layer containing the alternating copolymerization polymer (in general formula (I), R represents a monovalent hydrocarbon group or a substituted hydrocarbon group, D represents a polycyclic aromatic compound composed of carbon skeleton or a constitutional unit derived from a polycyclic aromatic heterocyclic compound containing a hetero atom, and n represents the number of repeating units and is 2 to 25).
