To provide a practically useful organic EL device which is driven at a low voltage and which has high efficiency and lifetime characteristics. The organic EL device includes one or more light-emitting layers between an anode and a cathode opposite to each other, in which at least one of the light-emitting layers contains a first host selected from a biscarbazole compound represented by the following general formula (1) and substituted with at least one triphenylene group, a second host selected from an indolocarbazole compound to which a nitrogen-containing 6-membered ring is bound, and a light-emitting dopant material, where m and n represent the number of repetitions, and m + n ≥ 1 is satisfied.
