An organic electroluminescence device using a compound represented by the following general formula in a light emitting layer has high luminous efficiency and can be manufactured at low cost [at least one of R1 to R8 and R17 is an electron donating group, Represents a hydrogen atom, at least one of R9 to R16 is an electron-withdrawing group having no unshared electron pair at the α-position, the other represents a hydrogen atom, Z represents a single bond or> C = Y, Y Represents O, S, C (CN) 2 or C (COOH) 2. However, when Z is a single bond, at least one of R9 to R16 is an electron-withdrawing group having no unshared electron pair at the α-position. ] |
