To provide an antimicrobial resin member which is excellent in heat resistance and hardly undergoes discoloration or degradation in quality by dispersing a fine antimicrobial metal powder comprising a silver or copper powder in at least the surface of a resin member.

Pref., the average particle size of the fine antimicrobial metal powder is lower than 1 μm; the content of the powder is 0.1-3.0 wt.%; and titanium oxide particles having photocatalytic activity are contained in at least the surface of the member. The metal powder is dispersed in at least the surface of the member by injection molding of a resin molding material or by driving the powder into at least the surface. The resin member may be formed from a resin selected from among various resins such as PE, PP, PS, PA, PEK, PEEK, ABS, or acrylic resins.
