A nitrogen-containing heterocyclic derivative represented by the following formula (1):
wherein any “12-a” groups of R
1
to R
12
are independently a hydrogen atom, a fluorine atom, a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms or a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms; any “a” groups of R
1
to R
12
are independently a single bond which is bonded to L
1
; L
1
is a single bond, a “b+1” valent substituted or unsubstituted hydrocarbon ring group having 6 to 30 ring carbon atoms or a “b+1” valent substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms;
HAr is a substituted or unsubstituted nitrogen-containing heterocyclic group; and
“a” and “b” are independently an integer of 1 to 4, and at least one of “a” and “b” is 1. Also disclosed is a nitrogen-containing heterocyclic derivative represented by the following formula (21) or (31):
