PROBLEM TO BE SOLVED: To provide a novel polymeric compound which is usable as a material of a light emitting layer, a hole injection layer, a hole transporting layer and the like, and to provide a polymeric light emitting element using the same. SOLUTION: The polymeric compound is characterized by comprising a repeating unit represented by formula (1) wherein X denotes an atom or divalent group which forms a five-membered ring or six-membered ring together with two atoms on A ring and two atoms on B ring, the atom or the divalent group contains at least one atom selected from the group consisting of oxygen atom, sulfur atom, selenium atom and silicon atom, A ring and B ring denote an aromatic hydrocarbon ring or heterocyclic ring, Ar1 denotes a divalent organic group having a divalent aromatic hydrocarbon group or heterocyclic ring skeleton, Ar2 and Ar3 denote a monovalent organic group having a monovalent aromatic hydrocarbon group or heterocyclic ring skeleton, R<SP>*</SP>denotes a linkage group and h denotes 0 or 1.
