PROBLEM TO BE SOLVED: To make it possible to impart antimicrobial, fungiproof and algaproof properties to articles consisting of dense materials by diffusing antimicrobial, fungiproof and algaproof components into the surface layer parts of the articles from the surfaces of the articles, thereby making it possible to impart the antimicrobial, fungiproof and algaproof properties to the surfaces of the articles without substantially forming coating layers. SOLUTION: The antimicrobial, fungiproof and algaproof articles 1 are formed by diffusing the antimicrobial, fungiproof and algaproof components 2 into the inside of surface layer parts of the articles from the surfaces of the articles. The inside of surface layer parts of the articles from the surfaces of the articles are conceivably attained by the antimicrobial, fungiproof and algaproof components 2 which are exposed on the article surfaces 3 and exhibit the antimicrobial, fungiproof and algaproof properties. These components are freshly exposed from the inside even if the article surfaces 3 are rubbed or eroded and, therefore, the degradation in the antimicrobial, fungiproof and algaproof properties does not arise. In either case, the antimicrobial, fungiproof and algaproof components 2 as represented by silver and copper diffuse into the inside and eventually exhibit the antimicrobial, fungiproof and algaproof properties on the surfaces 3 when these components are applied on the surfaces 3 of the articles 1, such as metals, glass and ceramics, and the articles are heated. |
