Abstract: The oxides-enclosed fine glass particles are arranged such that two or more pieces of at least two kinds of enclosing particles, which comprise oxides, double oxides, or salts of oxyacids, or double oxides or double salts thereof, are enclosed in each of the fine glass particles. The fine particles can be easily manufactured by mixing a powder material of glass with a powder material of oxides which comprise oxides, double oxides, or salts of oxyacids, or double oxides or double salts thereof that are not made to glass; converting the thus obtained mixture of the materials into a mixture in a vapor-state by supplying the thermal plasma thereto; and quickly cooling the mixture in the vapor-state. Highly-scattered fine particles of oxides can be easily obtained from the fine particles, and thus a plurality of kinds of fine particles of oxides can be evenly and uniformly mixed in a small amount with a mother material without being unevenly scattered.
