PCT No. PCT/JP83/00238 Sec. 371 Date Mar. 16, 1984 Sec. 102(e) Date Mar. 16, 1984 PCT Filed Jul. 25, 1983 PCT Pub. No. WO84/00555 PCT Pub. Date Feb. 16, 1984.A shielding composition has an electromagnetic wave shielding property and also an injection molding property. The composition comprises at least one kind of embedding material selected from a group consisting of plasticized vinyl chloride and acrylonitrile-butadiene-styrene resin, and copper or copper alloy fiber having a diameter of 1-100 mu m and a length of 0.5-10 mm embedded in said embedding material. The amount of the fibers is 30-70% by weight of the total composition.
