Ceramic product

Abstract

A ceramic product can include a decorative film containing noble metal elements and matrix-forming elements. The matrix-forming elements of such a ceramic product can include at least a rare earth element. Thus, in the ceramic product disclosed here, the mass concentration CN of the noble metal elements obtained in FESEM-EDS analysis of the surface of the decorative film can be 11% or more and 70% or less, and the ratio (CR/CN) of the mass concentration CR of the rare earth elements to the mass concentration CN of the noble metal elements can be 0.01 or more and 0.18 or less. Since the decorative film of such a ceramic product can have both alkali resistance and acid resistance at a high level, the ceramic product can have sufficient chemical resistance and can prevent the decorative film from being damaged during washing.
