PROBLEM TO BE SOLVED: To prepare a tape which does not require an extra release paper, and the like, while lowering the defect probability of a double-sided self-adhesive pad as much as possible. SOLUTION: A starting material tape 31 comprising a tape mount 311 and, arranged thereon, a self-adhesive layer 312 and a release layer 313 is manufactured. This starting material tape 31 is subjected to a half-cutting treatment to form a double-sided self-adhesive pad portion 314 and a separator portion 315 arranged in the neighborhood thereof. After a self-adhesive layer and a release layer of a portion 318 other than both portions 314 and 315 are removed, only the release layer 313 of the double-sided self-adhesive pad portion 314 is removed, leaving the double-sided self-adhesive pad 314 and a separator 315 thicker than the pad 314 are left on the tape mount 311. When this tape 31 is wound, the double-sided self-adhesive pad 314 is not brought into contact with the back surface of the tape 31 or, if contacted, the contact pressure is low owing to the presence of the separator portion 315, thus remarkably decreasing probability of transfer of the double-sided self-adhesive pad 314 to the back surface of the tape 31.
