Disclosed is a fullerene derivative represented by formula (1).n[In the formula, the ring A represents a fullerene skeleton having 60 or more carbon atoms; R 1 and R 2 are the same as or different from each other and independently represent a halogen atom, an alkyl group, an alkoxy group or an aryl group (provided that one, some or all of the hydrogen atoms contained in the alkyl, alkoxy or aryl group may be substituted by a halogen atom or halogen atoms); m represents an integer of 1 to 6; n represents an integer of 1 to 4; p represents an integer of 0 to 5; w represents an integer of 1 to 6; r represents an integer of 0 to 4; q represents an integer of 0 to 2; and v represents an integer of 0 to 3; provided that, when there are multiple R 1 's, the R 1 's may be the same as or different from each other; when there are multiple R 2 's, the R 2 's may be the same as or different from each other; when there are multiple m's, the m's may be the same as or different from each other; and when there are multiple q's, the q's may be the same as or different from each other.] |
