[Object] To improve adhesiveness of a cosmetic eyelid shaping tape for performing pseudo plastic surgery on an eyelid at inner-canthus and outer-canthus end portions of the eyelid by forming a constricted portion in the eyelid using resilient elasticity after extension of a base piece, constituting a tape-shaped member.[Solution] A double-eyelid-forming tape 1 includes a tape-shaped member 2 formed by laminating adhesive layers 4 on both surfaces of a base piece 3, and a pair of release sheet pieces 5 bonded to the adhesive layers. The release sheet pieces 5 each have groove-shaped tearable portions 6 and 7 that are easily tearable when being pulled in a longitudinal direction. The tearable portions each have a groove width gradually expanding from a groove bottom 61 or 71 toward the outer surface of the corresponding release sheet piece. The tearable portions include first tearable portions 6 formed at positions on the sides of a center O of the tape 1 closer to a first end 1a and a second end 1b, and a second tearable portion 7 at the center O and deeper than the first tearable portion.
