Provided is an effective technology which establishes high levels of both mask ventilation and mask collection characteristics for a mask fitted on the face of the wearer. A mask (1) is comprised of a mask body (10) which covers at least the mouth and the nose of the wearer, and a pair of ear fasteners (20) which extend out of both sides of the mask body (10) and catch onto the ears of the wearer. The mask body (10) includes a first fiber sheet and a second fiber sheet which are electret nonwoven sheets composed of a polypropylene fiber. The first fiber sheet is formed as a nonwoven sheet having an average fiber diameter of 0.5 to 3 mm and an areal weight of 1.5 to 5 g/m2. The second fiber sheet is formed as a nonwoven sheet with both an average fiber diameter and an areal weight greater than those of the first fiber sheet.
