Abstract
One embodiment relates to a charge transport polymer containing a molecular chain and terminal groups bonded to the molecular chain, wherein the terminal groups include a terminal group P containing a polymerizable functional group and a terminal group EW containing an aromatic hydrocarbon group substituted with an electron-withdrawing substituent, the terminal group P includes a terminal group represented by formula (P1) shown below, and among the carbon atoms contained in the ring of the aromatic hydrocarbon group, if the carbon atom that is bonded to the molecular chain is numbered 1, and numbers are assigned in order to the adjoining carbon atoms, then the electron-withdrawing substituent is bonded to a carbon atom numbered 1+2n (wherein n is an integer of 1 or greater).
