A mask is provided that can inactivate viruses adhering thereto even in the presence of lipids and proteins regardless of whether or not the viruses have an envelope. The mask can inactivate viruses adhering thereto and includes a mask body provided with a member used when the mask is worn and virus inactivating fine particles having a virus inactivating ability and held by the mask body. The virus inactivating fine particles are particles of at least one selected from the group consisting of platinum(II) iodide, palladium(II) iodide, silver(I) iodide, copper(I) iodide, and copper(I) thiocyanate.
