A phenanthrene derivative is represented by a formula (1) below. In the formula (1), Ar1 to Ar4 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. L represents a single bond, a substituted or unsubstituted benzene skeleton, naphthalene skeleton, biphenylene skeleton, fluorene skeleton, phenanthrene skeleton, fluoranthene skeleton, triphenylene skeleton, chrysene skeleton, phenyl-naphthalene skeleton or binaphthalene skeleton. R1 and R2 each represent a substituent, the number of which may be 0, 1 or more. R1 and R2 may be bonded in any positions of the phenanthrene skeleton. m, n, l and p each represent 0 or 1 while satisfying m+n+l+p≧1 (m,n≧l,p). a and b each represent an integer of 0 to 8.
