Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a novel substituted diphenylcarbazole derivative, a host material made of the derivative, and an organic electroluminescence (EL) element including the derivative.SOLUTION: The substituted diphenylcarbazole derivative is represented by formula (1) (wherein Rto Rare independently selected from a group consisting of hydrogen, fluorine, 1-4C straight-chain or branched alkyl group, and alkoxy group or alkyl amino group of which the alkyl portion is a 1-4C straight-chain or branched alkyl group; Rto Rare independently selected from a group consisting of hydrogen and 1-4C straight-chain or branched alkyl group; Aris either of diphenylamino group and triphenyl methyl group shown in formula (A); and Rto Rare independently selected from a group consisting of hydrogen, fluorine, 1-4C straight-chain or branched alkyl group, and alkoxy group or alkyl amino group of which the alkyl portion is a 1-4C straight-chain or branched alkyl group).
