The main body 10 may be formed to cover the entire face of the face while wearing the mask 100. As shown in FIG. 2, the body 10 includes an upper region 11 that covers a portion of the user's forehead, eyes, and nose, and a lower region 12 that covers the rest of the nose, mouth, cheeks, and chin. Can be distinguished.

The main body 10 is formed of a transparent or semi-transparent material so as to secure the user's field of view while wearing the mask 100 and to allow others to identify the user's face, facial expression, mouth shape, and the like. Details thereof will be described later.

Fixing strip 15 is formed on both sides of the body 10, the user can wear the mask 100 in a state in which at least a portion of the body 10 is in close contact with the face by holding the fixing strip 15 to the ear. The fixing strip 15 is formed of an elastic material (for example, silicon), and may be configured to correspond to users of various face sizes.

Alternatively, although not shown, the fixing strip 15 is formed to be adjustable in length, and may be configured to correspond to users of various face sizes.

One end of the fixing strip 15 extends from the edge of the upper region 11 of the body 10 so that both the upper region 11 and the lower region 12 of the body 10 can be in close contact with the face of the user. The other end is formed to extend from an edge of the lower region 12 of the main body 10.

In addition, both ends of the fixing strip 15 connected to the main body 10 are caught by the user's ears so that the edges of the upper area 11 and the lower area 12 of the main body 10 are more closely adhered to the face of the user. It may be formed to have a wider width than the central portion.

In FIG. 2, the mask 100 is formed to cover the entire face of the face, but according to the exemplary embodiment, the mask 100 may include only the lower region 12 so that the upper region 11 is omitted and the user's nose and mouth are covered. It may be formed to include.

Bonding between the UV blocking layer 130 and the endothelial layer 110 may be used, such as adhesive or heat, fusion using ultrasonic waves.

As shown in FIG. 15, after the endothelial layer 110 and the UV blocking layer 130 are bonded, a step of bonding the second layer on the UV blocking layer is performed. In the bonding of the second layer on the UV blocking layer, the outer skin layer 110 is bonded to the UV blocking layer 130. The UV blocking layer 130 and the outer skin layer 110 may also be bonded to the entire surface of the silver contact, or a portion (for example, an edge or a grid pattern) may be bonded. Bonding between the UV blocking layer 130 and the outer skin layer 110 may be used by the adhesive or heat, fusion using ultrasonic waves.

Although not shown, a plurality of endothelial breathing holes penetrating the endothelial layer 110 is formed in the endothelial layer 110, and a plurality of outer skin breathing holes penetrating the outer skin layer 120 are formed in the outer skin layer 120, and ultraviolet rays In the blocking layer 130, a plurality of intermediate breathing holes penetrating the ultraviolet blocking layer 130 may be formed.

The endothelial breathing hole, the outer skin breathing hole and the intermediate breathing hole may be a preformed, in the step of preparing the endothelial layer, preparing the outer skin layer and preparing the UV blocking layer, the endothelial layer 110, the outer skin layer 120 And the UV blocking layer 130 may be aligned so that at least one breathing hole of the endothelial breathing hole, the outer skin breathing hole and the intermediate breathing hole does not overlap with the other breathing hole.

Alternatively, the endothelial breathing hole, the outer breathing hole, and the intermediate breathing hole may be formed after the sealing of the endothelial layer and the outer skin layer. In this case, a plurality of needles (not shown) are allowed to penetrate the body sealed with the endothelial layer 110 and the outer shell layer 120, so that the endothelial breathing hole, the outer skin breathing hole, and the middle breathing hole are lined up as shown in FIG. 5. The breathing channel 240 may be aligned.
