Provided is an organic electroluminescent (organic EL) element that exhibits a high efficiency while having a low drive voltage, and that exhibits a high stability while being driven. The organic electroluminescent element contains, in a light-emitting layer formed between an anode and a cathode opposing each other, a first host selected from indolocarbazole compounds represented by general formula (1), a second host selected from carbazole compounds represented by general formula (2), and a light-emitting dopant material. Here, Ar2 and Ar3 are aromatic hydrocarbon groups, L1 is a direct bond or a phenylene group, and L2 is an o-phenylene group.
