A hydroxylated-fullerene-containing solution in which a hydroxylated fullerene is evenly nano-dispersed in a solvent removable at low temperature in a subsequent step is provided. The hydroxylated-fullerene-containing solution includes a continuous phase including a mixed solvent consisting essentially of tetrahydrofuran and water or including melted phenol, and at least one of a hydroxylated fullerene and a hydroxylated fullerene derivative that is dispersed as a dispersed phase in the continuous phase, wherein the number-standard average particle diameter of particles in the dispersed phase is 50 nm or less. This solution is applied onto a surface of a resin molding, and then tetrahydrofuran and water, as the mixed solvent, are removed to form a hydroxylated fullerene layer on the surface of the resin molding. Alternatively, this solution is mingled with a resin, and then the mixed solvent is removed to produce a hydroxylated-fullerene-containing resin composition.

Provided is a resin composition having excellent heat resistance by virtue of improved compatibility of a fullerene with a resin. Specifically, provided is a long-chain alkyl-etherified fullerene derivative, including: a fullerene skeleton formed of a spherical shell-shaped carbon molecule; and a long-chain alkyl group having 4 or more carbon atoms, which is bonded to the fullerene skeleton through an ether bond.
