An organic EL device includes: a pair of electrodes; and an organic layer sandwiched between the pair of electrodes. The organic layer includes a compound including layer, and the compound including layer includes a compound of 1,3-bis[N,N-bis{(4′-methylbiphen-4-yl)}amino]-5-N,N-bis(4-methylphenyl) aminobenzene. The heat resistance and the vapor deposition property of the organic layer containing the above tertiary amine compound can be improved.
