Sn-Cu ALLOY THIN FILM HAVING ANTIBACTERIAL PROPERTY, Sn-Cu ALLOY THIN FILM-FORMED ARTICLE HAVING ANTIBACTERIAL PROPERTY, AND METHOD FOR PRODUCING Sn-Cu ALLOY THIN FILM-FORMED ARTICLE HAVING ANTIBACTERIAL PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide an Sn-Cu alloy thin film having antibacterial properties in spite of its inexpensiveness, to provide an Sn-Cu alloy thin film-formed article coated with the same and having antibacterial properties, and to provide a method for securely and easily producing an Sn-Cu alloy thin film-formed article having antibacterial properties under the condition where an environmental load is not high.;SOLUTION: In the Sn-Cu alloy thin film having antibacterial properties, the containing ratio between Sn and Cu comprised in a thin film on the outermost surface layer formed on the ground of a base material satisfies 100-x [atomic%]:x [atomic%] (wherein, x is the content of Cu, and 10≤x≤90), and also, the thin film comprises 1 to 10 [mass%] SnO₂. Further, in the Sn-Cu alloy thin film having antibacterial properties, the total value of forming ratios at which the above Cu forms at least either Cu₆Sn₅ or Cu₃Sn is 10 to 100%.;COPYRIGHT: (C)2007,JPO&INPIT
