Summary:PROBLEM TO BE SOLVED: To provide a fabric for a mask having a high moisture retentivity in the fabric for mask using a polytetrafluoroethylene porous film. SOLUTION: This fabric for a mask has a laminated structure, and has the polytetrafluoroethylene porous film, and a woven or non-woven fabric having moisture retentivity. As the woven or non-woven fabric having moisture retentivity, a woven or non-woven fabric being formed of a natural fiber is preferably used. The fabric for mask preferably has a supporting layer as well. Also, the fabric for mask preferably has air permeability expressed by the number of flagyls of 150 cm/second or higher.
