Zusammenfassung:	PROBLEM TO BE SOLVED: To dissolve a problem of decreasing antimicrobial activities by losing silver by sublimation and evaporation while firing, and of damaging the quality of appearance of a ceramic product by the discoloration of the silver when allowing the ceramic product with a glaze to have antimicrobial activities by applying an antimicrobial agent containing the silver as an antimicrobial component. SOLUTION: When a glaze layer 14 is applied on the surface of a ceramic product 10 and the ceramic product is fired with the applied glaze layer to provide a ceramic product with graze, an antimicrobial agent layer 12 containing silver as an antimicrobial component is formed under the glaze layer of a top surface on the surface of the ceramic base material and the ceramic material with laminated layers are fired. The antimicrobial agent is migrated to the surface by utilizing the phenomenon of dispersion and migration of the antimicrobial agent in the molten graze to allow the ceramic product with the glaze to have the antimicrobial activities by the antimicrobial agent having reached the surface part.
