<p>PROBLEM TO BE SOLVED: To provide a mask having a high collection efficiency for liquid, harmful particles and virus, and high air permeability, and excellent in use feeling.SOLUTION: A mask 10 includes a covering body covering the nose and mouth and a mounting member arranged in the covering body. The covering body has a structure where a plurality of nonwoven fabrics 42A and 42B are laminated, and the plurality nonwoven fabrics 42A and 42B are integrated by heat compressing the outer periphery of the nonwoven fabrics 42A and 42B. Furthermore, nanofiber layers 44A and 44B are formed by an electrospinning method on at least two surfaces of inner surfaces positioned inside the mask, among surfaces which the plurality nonwoven fabrics 42A and 42B have. The total weight obtained by totaling the weight of each of the nanofiber layers 44A and 44B is in a range of 0.05-1.0 g/m, and an average fiber diameter of nanofiber forming each of the nanofiber layers 44A and 44B is in a range of 50-300 nm.</p> |
