Cover material, carrier tape, and taping apparatus

A cover tape comprising:

• a biaxially oriented resin layer,
• a heat sealant layer comprising a thermoplastic resin, and an electrically conductive fine powder dispersed therein and composed of barium sulfate particles, the surfaces of which are coated with tin oxide doped with antimony, said heat sealant layer having a surface resistivity of from 10.sup.5 to 10.sup.9 .OMEGA./.quadrature. and an electric charge attenuation time of a second or less, and
• an intermediate layer located adjacent to said heat sealant layer and between said biaxially oriented resin layer and said heat sealant layer and between said biaxially oriented resin layer and said heat sealant layer,
• wherein the intermediate layer is composed of multiple layers, among which at least one layer adjacent to the heat sealant layer comprises a resin composition including 30 to 50% by weight of an ethylene-.alpha.-olefin copolymer having a density of from 0.915 to 0.940 g/cm.sup.3, and 70 to 50% by weight of a styrene-butadiene block copolymer composed of 50 to 90% by weight of styrene and 50 to 10% by weight of butadiene.
