PROBLEM TO BE SOLVED: To provide a conductive nonwoven fabric which is thin in film thickness and high in strength, and has an electromagnetic wave shielding property in a wide frequency band.SOLUTION: A conductive nonwoven fabric comprises: a melt-blown nonwoven fabric which is formed by using, as a main component, a melt-liquid-crystal-forming wholly aromatic polyester having a melt viscosity of 20 Pa s or less at 310°C and satisfies following (A) to (G): (A) its average fiber diameter is 0.1 to 5 μm; (B) the number of film-like materials in the nonwoven fabric is 2 pieces/mmor less; (C) its longitudinal breaking length is 10 km or more and its transverse breaking length is 6 km or more; (D) its basis weight is 1.0 to 15 g/m; (E) its thickness is 5 to 50 μm; (F) its air permeability is 300 cc/cm/sec or less; and (G) the surface roughness Ra is 15 μm or less; and a metal film formed on the melt-blown nonwoven fabric.SELECTED DRAWING: Figure 1 |
