PROBLEM TO BE SOLVED: To provide a method of manufacturing a TAB tape, which has a simple manufacturing process, high-productivity, small consumption of protective film for adhesive agent, and can achieve low cost. SOLUTION: The method of manufacturing the TAB tape has peeling process where the protective film 14 is peeled off from a laminated film 11 having metal foil 12 and an adhesive agent layer 13 formed on the metal foil 12, to which the protective film 14 for protecting the adhesive agent layer is adhered, laminating process where the adhesive agent layer 13 of the laminated film 11 attached with the protective film and an insulating film 15 wider than the adhesive agent layer 13 are adhered with each other such that both end portions 20 of the insulating film 15 do not overlap the adhesive agent layer 13, sprocket hole forming process where sprocket holes 16 are formed on the both end portions 20 of the insulating film 15, and wiring pattern forming process where the metal foil 12 is etched to form a wiring pattern.
