NON-WOVEN FABRIC FOR ELECTROMAGNETIC WAVE SHIELDING MATERIALS AND ELECTROMAGNETIC WAVE SHIELDING MATERIAL

The problem of the present invention is to provide: a non-woven fabric base material for electromagnetic wave shielding materials， which can exhibit excellent electromagnetic wave shielding properties; and an electromagnetic wave shielding material. A non-woven fabric for electromagnetic wave shielding materials， which is a wet-type non-woven fabric comprising at least two types of stretched polyester-based short fibers and a non-stretched polyester-based short fiber， wherein the stretched polyester-based short fibers are independently selected from stretched polyester-based short fibers each having a fiber diameter of 3 μm or more and less than 12 μm and have different fiber diameters from each other and the non-stretched polyester-based short fiber has a fiber diameter of 3 to 5 μm inclusive; a non-woven fabric for electromagnetic wave shielding materials， which is a wet-type non-woven fabric comprising a stretched polyester-based short fiber having a fiber diameter of less than 3 μm and a non-stretched polyester-based short fiber having a fiber diameter of 3 to 5 μm inclusive， wherein the non-woven fabric has an areal fiber weight of 7 g/m 2 or less and a density of 0.5 to 0.8 g/cm3; and a non-woven fabric for electromagnetic wave shielding materials， which comprises a stretched polyester-based short fiber and a non-stretched polyester-based short fiber having a melting point of 220 to 250??C inclusive， wherein the peel strength (in the vertical direction) of the non-woven fabric is 2.0 N/m or more.
