Provided is a practically useful organic EL device having high efficiency and high driving stability while being at a low voltage. In an organic electroluminescent device including a light emitting layer between an anode and a cathode facing each other, at least one light emitting layer contains a host material containing two or more kinds of host compounds and at least one light emitting dopant, The host material includes a first host compound selected from indolocarbazole compounds having one or two indolocarbazole rings and a second host compound selected from carborane compounds having three or more carborane rings.
