The carbazole polymer containing the repeating unit represented by the formula (1) is excellent in the stability of one electron oxidation state. (In the formula (1), R 1 to R 4 each independently represent an alkyl group having 1 to 60 carbon atoms, a haloalkyl group having 1 to 60 carbon atoms, and the like, and Cz represents a carbazole skeleton represented by formula A bivalent group, Wherein R 5 represents a hydrogen atom, an alkyl group having 1 to 60 carbon atoms, etc., R 6 to R 11 each independently represent a hydrogen atom, a halogen atom or the like, and m is an integer of 1 to 10, And Ar represents a divalent aromatic ring or the like. |
