Abstract

See full text

A mask has a mask body and a pair of ear straps. The mask body includes an outer layer sheet and an intermediate layer sheet. The outer layer sheet is formed of hydrophobic fibers. The intermediate layer sheet is laid on the outer layer sheet so as to be located on a wearer's side of the outer layer sheet when the mask is worn. The intermediate layer sheet includes a first fiber layer which is formed of polyolefin fibers containing an inorganic antimicrobial agent and a second fiber layer which is formed of polyolefin fibers and has a larger fiber diameter than the first fiber layer. The fiber diameter of the first fiber layer is within a range of 0.5 to 2.8 μm and the ratio of a particle diameter of the inorganic antimicrobial agent with respect to the fiber diameter is within the range of 0.1 to 6.0.
