摘要： An object of the present invention is to provide a conductive sheet and an embossed carrier tape that can reduce detachment of carbon black and prevents deterioration of buckling strength. A conductive sheet for an embossed carrier tape for mounting an electronic component, in which the conductive sheet has a configuration in which a surface layer having conductivity is laminated on at least one surface of a core layer; the core layer and the surface layer each contain a common material constituted of only a combination of three types of polystyrene-based resins of styrene-butadiene copolymer resin, general purpose polystyrene resin, and high impact polystyrene resin; a common material constituting the core layer and a common material constituting the surface layer have the same compounding ratio; and the surface layer is formed by kneading carbon black in the common material.
