An organic electroluminescent element material characterized in being a compound represented by general formula (1). (In general formula (1), each of R1-R3 individually represents a substituent group. At least one of R1-R3 is a group represented by general formula (2). If a plurality of each of R1-R3 are present, each of R1-R3 may be the same or different, and may also be boned to each other to form a ring. n1 represents an integer of 0-8, n2 represents an integer of 0-3, and n3 represents an integer of 0-4. n1+n2+n3 is 1 or greater. Cbz represents a carbazolyl group. X represents an oxygen atom or a sulfur atom. L1 represents a single bond or a divalent linking group.)
