PROBLEM TO BE SOLVED: To solve the problem of warpage of a carrier tape by making the drum shape of a laminator roller into an arcuate carvature, and forming the drum shape of a compression roller on the curvature to be fitted in with this shape in a carrier tape manufacturing device through the lamination of metal foil, a film or the like. SOLUTION: A film or a sheet base material 4 is allowed to pass through a drying zone 5 and copper foil 6 is laminated by means of a laminator roller 1 having an arcuate drum part and a rubber roller 2 having an inverted-arcuate drum part fitting thereto via an adhesive. After being cooled by a cooling a roller 3, a laminate material 7 is taken up on a roller by putting the copper foil face outside. In this manner, since the cooling roller 3, guide roller, or winding roller have a lamination tape warped after nipping of the laminate tape, there exist no wrinkles in the tape. Therefore, even in the case of an adhesive undergoing large thermally hardening contraction, a quantity of warpage can be reduced, and a carrier tape with an excellent adhesive characteristics can be manufactured.
