PROBLEM TO BE SOLVED: To save a time require for polishing and to improve productivity, in the blade of a cutter used for a manufacturing method to perform half cut and full cut of a multilayer tape at the same process. SOLUTION: In the blade 1 of a cutter for forming a tape used for manufacture of a tape that a multilayer tape material 4 is half-cut or full-cut at the same process, and a cut blade part 3 for half-cut and a cut blade part 2 for full cut are individually formed to be combined into the single edge 1. This constitution, since only a necessary cut blade part can be polished, eliminates a need to re-grind all the edge and shortens a regulation time.
