Abstract

An object of the present invention is to provide an elongating tape that can be easily applied to the skin of a human body. SOLUTION: Since the tape body 40 has elasticity, the kneading tape 80 is stretched after pasting one end (front sticking side) of the tape main body 40 and the other end (rear pasting side). By sticking, the skin can be stretched by the elastic force of the tape body 40. For this reason, it is not necessary for the user to stretch the skin in advance, and wrinkle stretching can be performed only by sticking the wrinkle stretching tape 80. The kneading tape 80 includes cover films 36 a and 36 b cut between both ends of the tape main body 40. These cover films 36a and 36b carry the front sticking part and the rear sticking part of the tape main body part 40 until the sticking is completed, and suppress the deformation thereof. Thereby, sticking to skin can be performed easily and reliably. [Selection] Figure 1
