ク。[Claims for Utility Model Registration] 1. A mask characterized by being formed using a breathable resin material made of a porous resin film. 2. The mask according to claim 1, which is a utility model, and uses a breathable porous resin film that has been subjected to stretching treatment to form elongated pore-like voids between the fiber strips. '3 The long pore-like voids have a maximum pore diameter of 5 to 5 by the methanol bubble point method.
The mask according to claim 2 of the utility model registration claim, which has a diameter of 0 μm. 4. Request for utility model registration that the porous resin film is a stretched porous tetrafluoroethylene resin film having a continuous porous microstructure in which a large number of elongated fibers are arranged in narrow gaps and connected to each other by a large number of fine nodules. The mask according to any one of the ranges 1 to 3. 5 Stretched porous tetrafilament having a continuous porous microstructure which is stretched in the crossed directions to eliminate almost all micro nodules and whose fiber directions are crossed and the fibers are densified in a complex intertwined state. The mask according to any one of claims 1 to 3 of the utility model registration claim, which is an ethylene oxide resin film.
