PROBLEM TO BE SOLVED: To provide a mask capable of preventing unintended deformation of a shape of an air permeable face contact body and demonstrating the original dust-proof performance of the mask.SOLUTION: Since contact portions at the respective outer peripheries of a mask body portion 12 and an air permeable face contact body 13 are joined and integrated, and the air permeable face contact body is present on the inner air side of the mask body portion in such a form that the face contact body can be brought into contact with the face surface of a wearer, a mask can prevent intrusion of dust and viruses from a part between the mask body portion and the face surface of the wearer. Further, since the air permeable face contact body is formed by laminating a charged air permeable sheet and an air permeable support, and the air permeable support has a larger value of bending resistance than the charged air permeable sheet, even when a pressure toward the mask inner air side acts on the air permeable face contact body, the deformation to the mask inner air side of the charged air permeable sheet can be prevented, and the unintended deformation of the shape of the air permeable face contact body can be prevented. |
