Abstract

A mask includes a main body portion, a pair of ear strings, and an upper locking portion. The main body portion covers the mouth and has an upper end fixing point that is a part where the upper end part of ear string is fixed, and a lower end fixing point that is where the lower end part of each ear string is fixed. The pair of ear strings are on the right and left sides of the main body portion, and are put on the ears. The upper locking portion attaches to the main body portion. An intermediate part of each ear string is locked detachably to the upper locking portion. The upper locking portion is nearer the upper end fixing point than the lower end fixing point, and is inside the upper end fixing point with respect to the right/left direction of the main body portion.
