PROBLEM TO BE SOLVED: To provide an organic EL device, which has a high intensity of emission, exhibits stable performance even in repeated use and is easily fabricated, by using a new electron-transfer material having excellent electron-transfer property. SOLUTION: For the organic electroluminescent device with one or more organic compound layers held between a pair of positive and negative electrodes, at least one of which is transparent or translucent, at least one layer of the organic compound layers contains one or more of polymeric compounds obtained by using at least one of monomers represented by formula (1), [wherein, R1 represents a hydrogen atom or methyl group, and A represents any group selected from groups represented by formulae (2)-(6), (wherein, X represents an oxygen atom or the like, Y represents an oxygen atom or -COO(CH2)nO-, R4 and R5 each represents an alkyl group or the like, W represents -(CH2)nO- or the like, and Z represents an alkyl group or the like)].
