Disclosed is a mask having a face contact function, wherein a structure of a mask body can be directly changed by a wearer so that the mask body does not lift off the face regardless of the structure or size of the wearer's face. To this end, the mask body comprises a close-contact member including: a first cut line which is provided in the upper portion of the left end thereof and forms a first fastening protrusion according to an external force; a cut line for the first fastening protrusion, which is provided in the lower portion of the left end thereof and provides a space in which the first fastening protrusion is to be fitted so that the upper portion is maintained in a close contact with the lower portion; a second cut line which is provided in the upper portion of the right end thereof and forms a second fastening protrusion according to the external force; and a cut line for the second fastening protrusion, which is provided in the lower portion of the right end thereof and provides a space in which the second fastening protrusion is to be fitted so that the upper portion of the right end is maintained in close contact with the lower portion of the right end. According to the present invention, even when the mask body that is in contact with the curved contour of the cheeks lifts off due to the size or curve of the wearer's face, the mask body may easily come back into contact with the wearer's cheeks. In addition, when the wearer intensely moves and an external force is applied to the mask body, the contact-close state with the cheeks can be stably maintained.

Disclosed is a face mask formed from a transparent laminar body dimensioned to cover a user's mouth and nose, with fastening means and means for adding an antibacterial filter. The transparent body is formed by a concave curved case (1) with a perimeter edge (1a) that has an upper protuberance (1b) defining a recess (1c) that fits to the user's face, the lower part of the case (1) comprising a front thickened portion (1d) surrounding a hole that constitutes a transverse housing (2). According to the invention, the face mask includes a holder (3) which, in addition to acting as a means for coupling the antibacterial filter, can allow the inclusion of additional elements (4, 5, 6 or 7).
