A material for an organic electroluminescence device comprising a compound represented by the following general formula (1):

• where:
• Ar represents a group selected from an aryl group which has 6 to 24 ring carbon atoms and which may have a substituent, a carbazolyl group which may have a substituent, and a carbazolylphenyl group which may have a substituent;
• R1 represents a group represented by the following general formula (2) or (3);
• at least one of R2 and R3 represents a group represented by the following general formula (2) or (3), and the other represents a group represented by the following general formula (2), a group represented by the following general formula (3), a hydrogen atom, or an aryl group which has 6 to 24 ring carbon atoms and which may have a substituent;
• and
• R4 represents a hydrogen atom or an aryl group which has 6 to 24 ring carbon atoms and which may have a substituent:
• where R5, R6, and R7 each independently represent a hydrogen atom or a substituent.
