PROBLEM TO BE SOLVED: To provide a cover tape for a carrier tape which is excellent in workability, light transmissivity, and transparency. SOLUTION: In manufacturing a cover tape in which a polyethylene terephthalate resin layer, a low-density polyethylene resin layer, and an ethylene- vinyl acetate copolymer resin layer are laminated in this order, the low-density polyethylene resin is extrusion-laminated on the polyethylene terephthalate resin layer using a cooling roll of 0.15-3.0μm in mean ten-point surface roughness (RZ) in accordance with JIS B 0601, and the ethylene-vinyl acetate copolymer resin is extrusion-laminated.
