摘要： An electromagnetic wave absorbing sheet S is disclosed. The absorbing sheet S includes a laminated-structural layer of a nonwoven fabric sheet 10 and a metallic layer 22 such as iron, aluminums, copper or their alloy which is disposed on a bottom surface of the metallic layer 22. The nonwoven fabric sheet 10 includes non-metallic fibers 16 having no binding faculty, non-metallic binding fibers 14 having binding faculty which are melted by heat to bind neighboring fibers, and metallic fibers 12 having an irregular cross-section and being produced by shaving a metallic wire or rod, that are dispersed uniformly in the nonwoven fiber layer or layers.
