To provide an antibacterial transfer film that has a good detachability (transferability) and can form a layer having a sufficient antibacterial property.SOLUTION: The antibacterial transfer film has a substrate and a copper-tin alloy layer arranged on the substrate. The copper-tin alloy layer comprises at least an alloy of copper and tin, and has, in the depth direction, a region A having a relatively low oxygen atom content and a region B provided between the region A and the substrate and having a relatively high content of the oxygen atom.SELECTED DRAWING: Figure 1 【課題】良好な剥離性（転写性）を有し、かつ十分な抗菌性を有する層を形成することができる抗菌性転写フィルムを提供する。【解決手段】抗菌性転写フィルムは、基材と、前記基材上に配置された銅−錫合金層とを有する。銅−錫合金層は、少なくとも銅と錫の合金を含み、その深さ方向に、酸素原子の含有量が相対的に少ない領域Ａと、前記領域Ａと前記基材との間に設けられ、前記酸素原子の含有量が相対的に多い領域Ｂとを有する。【選択図】図１
