(Amendments Included) SUBJECT of the Invention The nonwoven fabric base material for electromagnetic shielding materials and electromagnetic shielding material which can express outstanding electromagnetic shielding are provided. PROBLEM to be solved The nonwoven fabric for electromagnetic shielding materials contains the extending|stretching polyester-type short fiber of less than 3 micrometers of fiber diameters， and the non-expanded polyester-type short fiber of 3 micrometers - 5 micrometers of fiber diameters， A fabric weight is 7 g/m 2 or less， It is a wet-laid nonwoven fabric which is a density of 0.5-0.8 g/cm 3. The nonwoven fabric for electromagnetic shielding materials also contains an extending|stretching polyester-type short fiber and the non-expanded polyester-type short fiber of 220 degreeC to 250 degreeC of melting|fusing point， and peeling strength (vertical direction) is 2.0 N/m or more.
