Abstract: Provided is a conductive nonwoven fabric, including a meltblown nonwoven fabric made from a melt liquid-crystal-forming wholly aromatic polyester having a melt viscosity at 310° C. of less than or equal to 20 Pa·s and satisfying (A) an average fiber diameter from 0.1 μm to 5 μm, (B) two or less film-like objects existing per 1 mm2 of the nonwoven fabric, (C) a breaking length in a warp direction of greater than or equal to 10 km and a breaking length in a weft direction of greater than or equal to 6 km, (D) a basis weight from 1.0 g/m2 to 15 g/m2, (E) a thickness from 5 μm to 50 μm, and (F) an air permeability of less than or equal to 300 cc/cm2/second, and a metal coating film formed on the meltblown nonwoven fabric.
