Abstract: To provide a mask capable of maintaining a state where antibacterial/antiviral properties do not deteriorate under any condition.SOLUTION: There is provided a mask/a masking gauze-integrated antimicrobial/antiviral mask obtained by using a phosphor bronze alloy powder. The phosphor bronze alloy powder having antibacterial property is composed of 1.05 wt.% of tin, 0.09 wt.% of phosphorus, and the balance copper with inevitable impurities. The phosphor bronze alloy powder is put into a mixture of water and a binder. After sufficient stirring, the obtained solution is uniformly carried on the surface of a first layer of masking gauze layers (eight-ply weave) by spraying using a spray gun or the like. The carried phosphor bronze alloy powder has an antibacterial property equal to or more than that of a phosphor bronze alloy thin-film plate. This carried phosphor bronze alloy powder can keep its antibacterial property for a long period of time. Only by being carried only on the first layer located at the surface of the masking gauze layers (eight-ply weave is generally used in the conventional mask), when the carried portion is brought into contact with the mask body, the antibacterial property spreads over a contact portion where the carried portion contacts, and such a state as if the mask entirely has an antibacterial property is created.SELECTED DRAWING: Figure 7
