Problem to be solved: to provide an antimicrobial substrate that is excellent in antimicrobial property and is excellent in transparency, and can maintain characteristics such as transparency of the substrate and color of the surface of the substrate.Solution: the cured material of a binder containing a copper compound and a photopolymerization initiator (a cured material of an electromagnetic wave curable resin) 12 is fixed to the surface of the base material 11, and at least a part of the copper compound is exposed from the surface of the hardened material 12 of the binder, and the photopolymerization initiator is a polymerization of an alkylphenone system Antimicrobial substrate 10 containing initiator and benzophenone polymerization initiators.Diagram【課題】抗微生物性に優れるとともに、透明性等に優れ、基材の透明性や基材表面の色彩等の特性をそのまま維持することが可能な抗微生物基体の提供。【解決手段】基材１１の表面に、銅化合物及び光重合開始剤を含むバインダの硬化物（電磁波硬化型樹脂の硬化物）１２が固着し、銅化合物の少なくとも一部は、バインダの硬化物１２の表面から露出しており、光重合開始剤は、アルキルフェノン系の重合開始剤およびベンゾフェノン系の重合開始剤を含む抗微生物基体１０。【選択図】図１
