Preferably, the first sheet further comprises a first fold line and the second sheet further comprises a second fold line extending from a first side of the first sheet The second fold line extends from one of the second sides of the second sheet to the other second side, and the second fold line is connected to the first fold line.

Preferably, the second bonding wire is formed by extending the adjacent ends of the second ends of the second body and the first ends of the first body toward the first fold line or the second fold line. And the second bonding wire and the first bonding wire intersect at the first folding line and the second folding line.

Preferably, the distance between the two side edges of the first sheet is decreasing from the first fold line toward the first end portions.

Preferably, the first fold line divides the first sheet longitudinally; the second fold line divides the second sheet longitudinally.

Preferably, the foldable three-dimensional mask further comprises a bead which is laterally disposed on the first side of the first sheet relative to the second sheet.

Preferably, the first fold line divides the bead longitudinally.

Preferably, the fixing portion, the first bonding wire, the second bonding wire or the oblique bonding wire are joined by hot melt bonding.

The collapsible three-dimensional mask of the present invention only includes two sheets of the first sheet and the second sheet, so that the first sheet can be obtained only by the first bonding line formed by one hot-melt pressing process. And a second sheet combination. In addition, the fixing portion of the second piece, the first bonding wire, the second bonding wire, and the oblique bonding wire may cause the second ends of the second body to be lifted away from the opposite second ends, respectively. Form a foldable three-dimensional mask. Therefore, the foldable three-dimensional mask of the present invention solves the prior art foldable three-piece three-dimensional mask, and needs to be subjected to a secondary hot-melt pressing process, so that the three sheets are combined with each other, and the user must use the same during use. The two pieces of the body can form a three-dimensional mask.
