Abstract: The present invention aims to provide a conductive layered body having excellent solvent resistance and scratch resistance as well as a low haze value and a significantly high light transmittance. The present invention relates to a conductive layered body including, as an outermost layer thereof, a conductive layer containing a conductive fibrous filler, wherein the conductive layered body has a Martens hardness of 150 to 3,000 N/mm2 as measured at an indentation depth of 100 nm from a surface, and a ratio, in atomic percentage, of a conductive material element constituting the conductive fibrous filler on an outermost surface-side surface of the conductive layer is 0.15 to 5.00 at %.
