PROBLEM TO BE SOLVED: To provide a manufacturing process of glass in which microparticles of a semiconductor compound containing sulfur, selenium or tellurium are dispersed and microparticle dispersion glass which does not require heat treatment, and an ultraviolet cut filter using the glass. SOLUTION: The manufacturing process of the microparticle dispersion glass comprises mixing glass as a glass matrix, a compound containing a substitution substance including at least one kind selected from sulfur, selenium and tellurium and zinc oxide to obtain a mixture, melting the mixture by heating and cooling it so that the oxygen in the zinc oxide is substituted with the substitution substance through substitution reaction and miroparticles consisting of zinc and the substitution substance is deposited in the glass. Preferably, the concentration of the substitution substance to be added in the mixture such as sulfur, selenium and tellurium is so adjusted in advance as to obtain a desired particle size.
