In Fig. 3, the mask body 11 of the present embodiment has a multi-layered structure, and is sequentially laminated from the inner side surface (the surface contacting the inner side of the face) of the mask 10 to the outer side surface (the side opposite to the inner side surface). The water absorbent sheet 114 and the porous resin film 115 are formed.

The water-absorbent sheet 114 is a sheet that absorbs the moisturizing liquid W and supplies moisture to the oral cavity and/or the nasal cavity of the user. In addition, the porous resin film 115 suppresses the film in which the moisturizing liquid W in the water absorbent sheet 114 oozes out to the outer surface (rewetting) of the mask body 11. The mask comprising at least the water-absorbent sheet 114 and the porous resin film 115 has the effect of the present invention as described above, that is, it can effectively prevent the user's mouth and/or nasal cavity from drying, and can also inhibit the moisturizing liquid W from oozing to the mask. The outer side surface of the body 11.

The water absorbent sheet 114 and the porous resin film 115 will be described. The water-absorbent sheet 114 is disposed near the center of the mask 10, and when the mask 10 is used, it absorbs the moisturizing liquid W described below to supply moisture to the oral cavity or nasal cavity of the user. In order to supply sufficient water to the oral cavity or the nasal cavity for several hours, it is preferable to maintain 5 ml or more of the following moisturizing liquid W, and it is more preferable to maintain 7 ml or more.

Examples of the fiber material of the water absorbent sheet 114 include a hydrophilic fiber and a blend of a hydrophilic fiber and a synthetic fiber. Examples of the hydrophilic fiber include pulp, enamel, cotton, and the like. Examples of the synthetic fiber include polypropylene, polyethylene, and polyester.
