Disclosed is a method for producing a fluorescent plastic product that exhibits stable luminous characteristics with good luminous efficiency by dispersing fine particles made of metal having a particle size of 1 nm or less in a thermosetting plastic monomer or a thermoplastic resin in a liquid phase. To provide. Gold metallized by vaporizing a metal selected from Au, Ag, Cu, Pt, Pd and Ti, for example, gold (Au) by sputtering, and vaporizing it with a polythiol compound as a thermosetting plastic monomer. The isocyanate compound is added by stirring and stirring, and is cured in a predetermined mold. As a result, it is possible to obtain a plastic in which nanoparticles of 1 nm or less are dispersed.
