Next, in step ST103, the hygiene mask HM is worn and the hygiene face guard 1 is fixed to the user's head.

Finally, in step ST103, the folding strength of the folding lines 16b to 16g is adjusted, and the shape is adjusted so as to follow the face.

As described above, the hygienic face guard 1 can be easily used and its shape can be adjusted. Further, if the product is sold in the form of a sheet and is formed into a shape that covers the face and overhead when used, it can be packaged compactly, so that the transportation cost can be suppressed.

As described above, the hygienic face guard 1 can be easily and inexpensively manufactured, and can prevent droplets from above the user from adhering to the user. In addition, it is excellent in that it can be made into various forms by appropriately providing cuts and fold lines, and that the effect can be imparted to the hygienic face guard 1 by using a sheet-like material having a specific effect. ing.
