    • Disclosed is an organic electroluminescence device comprising one layer or two or more layers of organic layer sandwiched between an anode and a cathode wherein: at least one of the organic layers comprises a phosphorescent compound and a polymer; the polymer comprises a structural unit derived from a monomer represented by the following formula (1) and a structural unit derived from a monomer having heterocycle(s) containing two or more heteroatoms. (I) (In the formula, R1-R27 each represents independently a hydrogen atom, a halogen atom, a cyano group, an amino group an alkyl group having 1 to 10 carbon atoms or an alkoxy group having 1 to 10 carbon atoms; within each of the groups R1-R4, R5-R9, R10-R14 and R15-R19, two groups bonding to adjacent carbon atoms in a benzene ring may bond to each other forming a fused ring; X1 represents a single bond, an oxygen atom (—O—), a sulfur atom (—S—), —SO—, —SO2—, —NR— (R represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or a phenyl group), —CO— or a divalent organic group having 1 to 20 carbon atoms (the organic group may be substituted with an atom or a group selected from the group consisting of an oxygen atom (—O—), a sulfur atom (—S—), —SO—, —SO2—, —NR— (R represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or a phenyl group) and —CO—); Y1 represents a polymerizable functional group; and p represents 0 or 1.)
