Furthermore, since the synthetic fiber fabric 11 is fused at the notch 15 in each of the side edges 3c and 3c, the mask body 3 is fused with the synthetic fiber fabric 11 and the cellulose fabric 9 at the fused portion. It is easy to suppress the positional deviation between the two fabrics, to easily ensure the strength of the mask 1 more reliably, and to maintain the shape retention of the three-dimensional structure of the mask body 3. Therefore, the mask 1 according to this embodiment can easily ensure the fit of the mask body 3 to the face.

  Moreover, even if the notch part formation area 17 touches a wearer's face, since the said part does not have the embossed part 35, the mask 1 which concerns on this embodiment is hard to give irritation | stimulation to a wearer's face, and a wearer It is easy to suppress a sense of incongruity on the face.

  Moreover, since the strength of the mask main body 3 can be ensured by the auxiliary embossed portion 37, the shape retaining property of the three-dimensional structure of the mask main body 3 can be more easily maintained. Therefore, the mask 1 according to the present embodiment has the mask main body 3. It is easy to ensure the fit to the face more reliably.

  Further, since the cellulose fabric 9 is covered with the synthetic fiber fabric 11 in the vicinity of the lower end edge 3b by the first folded portion 31, the cellulose fabric 9 is unlikely to directly contact the wearer's face in the vicinity of the lower end edge 3b. And the mask 1 which concerns on this embodiment is easy to suppress the discomfort in a wearer's face.

  Further, since the rigidity in the vicinity of the lower end edge 3b is increased by the second folded portion 33, the shape retaining property of the three-dimensional structure of the mask main body 3 is enhanced, and the mask 1 according to the present embodiment has the fitting property to the face of the mask main body 3. It is easy to ensure more reliably.
