PROBLEM TO BE SOLVED: To provide an electromagnetic wave shield material that has an excellent electromagnetic shield property, has no directivity in shielding performance, and can be processed into various forms. SOLUTION: The electromagnetic shield material is constituted such that a fibro-sheet includes a conductive short fiber and a nonconductive short fiber, the specific gravity (A) of the conductive short fiber is within a range of 0.9 to 3, the specific gravity (B) of the nonconductive short fiber is within a range of 0.9 to 3, and the ratio of the (B)/(A) is within a range of 0.5 to 2, and further, the content of the conductive short fiber is within a range of 0.1 to 60 wt.%.
