                            Provided is a charge transport material represented by the following general formula (1) or (2).
In the foregoing general formulae, each of L
1
and L
2
independently represents a connecting group; each of R and R
N
independently represents a substituent; each of R
1
and R
2
independently represents a substituent, provided that R
1
and R
2
do not represent an aryl group at the same time; each A independently represents a carbon atom or a nitrogen atom; n represents an integer of 2 or more and not more than 10; and each m independently represents an integer.
