A long cut line 21 extending along a virtual cutting line D is arranged in a central region A of an adhesive tape 1. The length of the long cut line 21 is made longer than a length of a second adjacent cut line 22 arranged in an adjacent region B and an outer cut line 23 arranged in an outer region C. The adjacent region B and the outer region C of the adhesive tape 1 have a tensile strength that can withstand the tensile stress generated when the adhesive tape 1 is fed out.
