ABSTRACT:
A disposable sanitary mask comprises a covering panel section adapted to cover the wearer's nose and mouth and a pair of ear-looping panel sections which are respectively formed of nonwoven fibrous fabric. The covering panel section has a central rigid region formed vertically extending across a front surface thereof and side rigid regions defined vertically extending across the front surface thereof, a rigidity of these regions being higher than that of the remaining region of the covering panel section. Therefore, the mask can keep at least the covering panel section from losing its shape.
