Abstract
After an ultrafine particle is disposed on a giant fullerene by driving the ultrafine particle 1 using an electron beam, the ultrafine particle is enclosed in a core hollow portion of the giant fullerene, by contracting the giant fullerene with the electron beam irradiation. Or a metal ultrafine particle composed of an active metal is enclosed in the core hollow portion of the giant fullerene, by irradiating a high energy beam such as the electron beam to an amorphous carbon under existing of the active metal to form the giant fullerene in an irradiated portion, and by contracting the giant fullerene with the irradiation of the high energy beam such as the electron beam.
