PROBLEM TO BE SOLVED: To provide a mask inner brought into close contact with the face preventing a mask from slipping out of place even if moving the mouth during wearing the mask. SOLUTION: Expansive members 8 are arranged along the edge of the upper part and lower part of a center projecting part 2 formed of a shape-holdable, flexible bowl-shaped sheet, to provide a nose upper part covering part 3 and a jaw covering part 4, and a waterproof reinforcing band 5 is disposed at the inner surface of the center projecting part 2. Accordingly, even if moving a mouth for a talk or the like during wearing a mask, the whole area surrounding the center projecting part 2 is freely deformed in response to the motion of the face, so that the center projecting part 2 is not influenced by the motion to always keep a projecting space, nor the projecting mask inner and the mask slip out of place. |
