PROBLEM TO BE SOLVED: To provide an antibacterial material having antibacterial effect by strong alkaline calcium hydroxide powder, and antibacterial deodorization effect by deoxidation of a silver particle, high in antibacterial effect by the calcium hydroxide powder when temperature is high, and capable of exhibiting antibacterial effect regardless of used conditions since the antibacterial deodorization effect by the silver particle is high under a dry state or a high temperature state.SOLUTION: The antibacterial material having a calcium hydroxide powder obtained by hydration of high temperature burned shell or shell of hen egg and having average particle diameter of 3.5 μm to 300 μm and pH of 12 to 13, and a silver particle having average particle diameter of 0.001 μm to 0.05 μm.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】水酸化カルシウム粉末の強アルカリ性による抗菌効果と、銀粒子の脱酸素による抗菌・防臭効果を有し、湿度が高いと水酸化カルシウム粉末による抗菌効果が高く、乾燥状態や高温状態では銀粒子による抗菌・防臭効果が高いため、使用条件にかかわらず抗菌性を発揮することができる抗菌材を提供すること。【解決手段】本発明の抗菌材は、高温焼成した貝殻又は鶏卵の殻を水和して得られる平均粒径が３．５μｍ～３００μｍでｐＨ１２～１３の水酸化カルシウム粉末と、平均粒径が０．００１μｍ～０．０５μｍの銀粒子とを有することを特徴とする。【選択図】 図１
