One embodiment of this invention is a charge-transport polymer comprising: a molecular chain; and a terminal group which binds to said molecular chain. The terminal group includes a terminal group P including a polymerizable functional group and a terminal group B which includes an aromatic hydrocarbon group substituted by a branched or annular substituent. With regard to the carbon atoms which make up the ring of hydrocarbon groups, if the number of the carbon atom which binds to the molecular chain is set to 1 and numbers are assigned in order to the adjoining carbon atoms, the branched or annular substituent is bonded to 1+2n (where n is an integer of 1 or more) carbon atoms. Un mode de réalisation de l'invention concerne un polymère à transport de charges, comprenant : une chaîne moléculaire; et un groupe terminal se liant à ladite chaîne moléculaire. Le groupe terminal comprend un groupe terminal P contenant un groupe fonctionnel polymérisable et un groupe terminal B contenant un groupe hydrocarboné aromatique substitué par un substituant ramifié ou annulaire. S'agissant des atomes de carbone constituant le cycle de groupes hydrocarbonés, si le nombre de l'atome de carbone se liant à la chaîne moléculaire est 1 et que des nombres sont attribués dans l'ordre aux atomes de carbone adjacents, le substituant ramifié ou annulaire est lié à 1+2n (n étant un entier de 1 ou plus) atomes de carbone. 一実施形態は、分子鎖と、該分子鎖に結合する末端基とを含み、前記末端基が、重合性官能基を含む末端基Ｐと、分岐状又は環状の置換基により置換された芳香族炭化水素基を含む末端基Ｂとを含み、前記芳香族炭化水素基の環を構成する炭素原子について、前記分子鎖に結合する炭素原子の番号を１とし、隣接する炭素原子に順に番号をつけたとき、前記分岐状又は環状の置換基が、１＋２ｎ（ｎは、１以上の整数である。）の炭素原子に結合している、電荷輸送性ポリマーに関する。
