Abstract:
1. An antimicrobial raw material comprising: a substrate layer made of resin, natural fiber or paper, the resin having a deflection temperature under load of 115° C. or below as measured in accordance with ASTM-D648-56 under a load of 1,820 kPa; and a copper-tin alloy layer disposed on the substrate layer, the copper-tin alloy layer containing 10 atom % to less than 40 atom % of tin, with remaining portion substantially consisting of copper, wherein the copper-tin alloy layer has a thickness of 5 nm to 200 nm; and the copper-tin alloy layer has Q value (Ω/(nm·Cu atom %)) of 0.001 to 0.007, the Q value being obtained by dividing a sheet resistance (Ω) of the copper-tin alloy layer by a product of thickness of (nm) and copper atom content (Cu atom %) of the copper-tin alloy layer.
