PROBLEM TO BE SOLVED: To provide a blue light-emitting polymer which has a main chain of polyarylene introduced with indolocarbazole units and to provide an organic EL element using the polymer. SOLUTION: The invention relates to a polymer expressed by formula 1. (In the formula Ar is selected from a group comprising an aryl and heteroaryl group, R<SB>1</SB>, R<SB>2</SB>, R<SB>3</SB>and R<SB>4</SB>are each independently selected from a group comprising H, an alkyl group, an alkoxy group, an aryl group, an arylalkyl group, an aryloxy group, heteroaryl group, heteroarylalkyl group, heteroaryloxy group, cycloalkyl group, heterocycloalkyl group, n is a real number of 0.01-0.99, wherein each functional group optionally substituted with other functional groups).
