Abstract: An excellent antibacterial property is afforded upon a metallic article by simple steps of coating a dispersion liquid or a solution of fine particles made of an antibacterial ingredient on the surface of the metallic article and pressing the resulting coated surface of the metallic article under a non-heated condition or rubbing the resulting coated surface of the metallic article. In addition, a conventional rolling step or the like can be used itself without any change in the above treatment, which is economically extremely advantageous. Furthermore, since the antibacterial metallic article according to the present invention is obtained under the non-heated condition, the antibacterial ingredient is not deteriorated. Further, since the antibacterial property is not lost through some abrasion, excellent antibacterial property can be exhibited over an extended time period. Further, there is no fear that surface characteristics of the metallic article, for example, a tone of color will change.
