An object of the present invention is to provide a novel fullerene derivative usable in n-type semiconductor materials for organic thin-film solar cells and the like. The object is achieved by a fullerene derivative represented by formula (1)
wherein R
1
represents aryl optionally substituted with at least one substituent, R
2
represents an organic group, R
3
represents an organic group, with the proviso that at least one of R
2
and R
3
is alkyl optionally substituted with at least one substituent or alkyl ether optionally substituted with at least one substituent, R
4
represents hydrogen or an organic group, and a ring A represents a fullerene ring.
