SOLUTION: The simple mask is formed of a variable forming member generally in a semicylindrical shape for wearing and using so as to cover almost an entire face from a forehead to a chin. In the variable forming member, an edge part of a vertical ridge of the roughly semicylinder and a roughly semicylindrical mask body, which is contacted with a face is composed of an elastic member having a specified thickness.
