Provided are a nitrogen-containing heterocyclic derivative having a specific structure containing a pyrazine skeleton in the center thereof, a hole injecting material or hole transporting material for an organic electroluminescence (EL) device, a light emitting material for an organic EL device, and an electron injecting material or electron transporting material for an organic EL device each containing the nitrogen-containing heterocyclic derivative, an organic EL device which includes one or a plurality of organic layers interposed between a cathode and an anode and in which at least one layer of the organic layers contains the nitrogen-containing heterocyclic derivative, and an apparatus including the organic EL device. The organic EL device shows high luminous brightness and high luminous efficiency even at a low voltage as compared with a conventional device.
