<p>The present invention provides an organic EL material improving light-emitting efficiency and realizing long lifetime. The present invention includes an organic EL material represented by the following Formula (1). In Formula (1), X is a monovalent group represented by the following Formulae (2) to (14), each of Ar independently represents an aryl group or a heteroaryl group having 6-18 carbon atoms, R is an aryl group or a heteroaryl group having 6-18 carbon atoms, or an alkyl group having 1-12 carbon atoms, and a-c are a, b, c≠0 (a natural number satisfying a < 3, b < 3, c < 3).
