PROBLEM TO BE SOLVED: To provide a newπ-conjugation-based polymer useful as a polymer material for an organic thin film EL element having an excellent luminescence characteristics and excellent in durability and also a semiconductor material for an organic transistor. SOLUTION: This polymer has a recurring unit expressed by general formula (I) [wherein, Ar is a substituted or non-substituted divalent aromatic hydrocarbon or aromatic heterocyclic ring group; R<SP>1</SP>to R<SP>4</SP>are each H, a substituted or non-substituted alkyl or alkoxy; and (x), (y) are each independently 0 or 1].
