Abstract:
1. An antimicrobial raw material comprising: a substrate layer; and a copper-tin alloy layer disposed on the substrate layer, the copper-tin alloy layer containing over 60 atomic % to 90 atomic % of copper and 10 atomic % to less than 40 atomic % of tin, wherein the copper-tin alloy layer comprises a Cu a Q value (Ω/(nm·Cu atomic %)) obtained by dividing a sheet resistance (Ω) of the copper-tin alloy layer by a product of a thickness of the copper-tin alloy layer and a copper content (Cu atomic %) in the copper-tin alloy layer is 1.5×10
