PROBLEM TO BE SOLVED: To provide a method for producing a substrate including a film having an antimicrobial property; and to provide an article produced by the method.SOLUTION: A method for producing a substrate including a film having an antimicrobial property, in which a texture of a surface having an exposed metal, for example, copper or a copper alloy contributes to an antimicrobial property, includes steps for: (i) preparing a substrate including an outside thermal spray metal coat having a surface cavity; and (ii) reducing a depth of the cavity by mechanically wearing the coat, in which the cavity or a hollow on the surface can be coated or partially coated with an organic polymer, and the polymer can contain an antimicrobial agent.SELECTED DRAWING: Figure 16【課題】抗微生物特性を有する皮膜を備えた基材を製造する方法、及びその方法で作製された物品の提供。【解決手段】露出した金属、例えば銅又は銅合金を有する表面のテクスチャが抗微生物特性に寄与し、(i)表面キャビティを有する外側溶射金属コートを備えた基材を用意するステップと、(ii)コートを機械的に摩耗させて、前記キャビティの深さを低減するステップを含み、表面のキャビティ又はくぼみを有機ポリマーで被覆又は部分被覆することができ、ポリマーは抗微生物剤を含有することができる。【選択図】図16
