PROBLEM TO BE SOLVED: To provide an amine compound suitable as a hole injection transport material, etc., of an organic electroluminescent element and having high heat resistance and to provide the organic electroluminescent element using the amine compound and having excellent stability, durability and heat resistance. SOLUTION: The amine compound is represented by general formula (1) [wherein, X<SB>1</SB>denotes an N-carbazolyl group or an NAr<SB>1</SB>Ar<SB>2</SB>(wherein, Ar<SB>1</SB>and Ar<SB>2</SB>denote each an aryl group); X<SB>2</SB>denotes an NAr<SB>3</SB>Ar<SB>4</SB>(wherein, Ar<SB>3</SB>and Ar<SB>4</SB>denote each an aryl group); Z<SB>1</SB>, Z<SB>2</SB>, Z<SB>3</SB>, Z<SB>4</SB>, Z<SB>5</SB>and Z<SB>6</SB>denote each a hydrogen atom, a halogen atom or an (O)n-Z group (wherein, Z denotes a straight-chain, branched or cyclic alkyl group or an aryl group; and n denotes 0 or 1); R<SB>1</SB>and R<SB>2</SB>denote each a hydrogen atom, a straight-chain, branched or cyclic alkyl group, an aryl group or an aralkyl group; and at least one of Ar<SB>1</SB>to Ar<SB>4</SB>denotes a phenanthrenyl group].
