SOLUTION: A mask 1 has a main body part 2 and ear strings 3. Inside the main body 2, an auxiliary piece 10 formed into stereoscopic gathers from a gas permeable material sheet 11 is fitted while being turned longitudinally. When the mask 1 is mounted, the gap between the main body 2 and the cheeks is closed by the auxiliary piece 10. Besides, when a lateral auxiliary piece 20 is fitted at the upper part of inner surface of the main body part 2 and this auxiliary piece 20 is formed into stereoscopic gathers from a gas permeable material sheet 21, at the time of wearing the mask, the gap between recessed parts on both the sides of nose and the main body part 2 is closed.
