ABSTRACT:
A mask is formed of a rectangular mask main body made of a ventilating material and a longitudinal elastic member stored in and attached to the mask main body. The mask main body is formed of a rectangular rear side member facing at least a nose and a mouth of a wearer, and a rectangular front side member disposed over the rear side member. The mask main body has folded portions folded in a direction parallel to long sides of the mask main body. End portions of the folded portions are located on short sides and bound thereat. The longitudinal elastic member extends along the long sides of the mask main body and has end portions arranged not to contact the short sides of the mask main body. Since the end portions of the elastic member do not contact the user in use, the mask can be worn comfortably.
