A phenanthrene derivative is represented by a formula (1) below. In the formula (1), Ar
1
and Ar
2
each represent an aromatic hydrocarbon ring group having 6 to 18 carbon atoms for forming the ring. The aromatic hydrocarbon ring group contains none of anthracene skeleton, pyrene skeleton, aceanthrylene skeleton and naphthacene skeleton. R
1
represents a substituent, the number of which may be 0, 1 or more. R
1
may be bonded in any position of the phenanthrene skeleton. n and m each represent an integer of 1 to 3. k represents an integer of 0 to 8.
