PROBLEM TO BE SOLVED: To provide a new copolymer which has high solubility and is suitable for a photoelectric conversion element.;SOLUTION: The copolymer includes a repeating unit represented by formula (1A) and a repeating unit represented by formula (1B). (In formula (1A), R¹ and R² each independently represent hydrogen atom or a substituent, in which at least one of R¹ and R² is a substituent, and R¹ and R² may be mutually bonded to form a ring). (In formula (1B), Q represents a 14-group element, X¹ and X² each independently represent oxygen atom or sulfur atom, R³-R⁶ each independently represent hydrogen atom, halogen atom or a hydrocarbon group which may have hetero atom, and adjacent ones of R³-R⁶ may be bonded to form a ring).;COPYRIGHT: (C)2013,JPO&INPIT
