PROBLEM TO BE SOLVED: To provide an antifouling processing method of an antibacterial product having a novel constitution capable of forming an antifouling processing film not lowering considerably antifouling performance, and not damaging designability of an antifouling surface.SOLUTION: A perforated masking member 13 is arranged on an antifouling surface 11a of an antibacterial product, and an antifouling processing film 15 is formed by physical vapor deposition (PVD). The antifouling processing film 15 is a transparent thin film not lowering designability of the antifouling surface. As an antibacterial product to which this invention is applied, a washing implement, a cosmetic container, a writing implement, a cooking implement, a knob of a kitchen instrument-door or the like are enumerated.COPYRIGHT: (C)2015,JPO&INPIT【課題】抗菌性能を余り低下させず、かつ、抗菌面の意匠性を損なわない防汚処理膜を形成できる新規な構成の抗菌製品の防汚処理方法を提供する。【解決手段】抗菌製品の抗菌面11aに穴明きマスキング部材部材13を配し、防汚処理膜15を物理的蒸着(PVD)により形成する。該防汚処理膜15は、抗菌面の意匠性を低下させない透明薄膜である。本発明を適用する抗菌製品としては、洗面用具、化粧品容器、筆記用具、料理用具、厨房器具・ドアのノブ類等がある。【選択図】図1
