Claim:
1. An organic electroluminescence device, comprising: a pair of electrodes composed of an anode and a cathode; a light emitting layer between the electrodes; and an organic layer which is adjacent to the light emitting layer between the light emitting layer and the cathode, on a substrate, wherein the light emitting layer comprises at least one compound represented by the following Formula (1), and the organic layer adjacent to the light emitting layer, which is on the cathode side of the light emitting layer, comprises at least one hydrocarbon compound represented by Formula (Tp-3): in Formula (1), R in the case where R each of R in the case where each of R the substituent Z represents a phenyl group, n1 represents an integer of 0 to 2, each of n2 to n5 independently represents an integer of 0 to 1: in Formula (Tp-3), L represents a phenyl group, which may be substituted with a C1-C5 alkyl group or a phenyl group, or an n-valent linking group formed by combining these groups, and n represents an integer of 1 to 3.
