An organic electroluminescent element material containing a compound having a structure represented by Formula (1):
wherein D and A each represent a substituent; X and Y each represent a carbon atom, a nitrogen atom, an oxygen atom or a silicon atom which may have a hydrogen atom or a substituent; and at least one of X and Y is a carbon atom, provided that in the substituent represented by D, when a structure in which a linking portion to a linker (X—Y) is replaced with a hydrogen atom is D-H; and in the substituent represented by A, when a structure in which a linking portion to the linker (X—Y) is replaced with a hydrogen atom is A-H, D-H has a higher energy level of HOMO than A-H, and A-H has a lower energy level of LUMO than D-H.
