[Object] In a piece of cosmetic eyelid-shaping tape used for performing pseudo shaping on an eyelid by forming a constricted portion on the eyelid by using elastic contractility when the tape-shaped member is stretched, to improve adhesiveness of the tape-shaped member to skin on an inner corner side of the eyelid of the eye (and/) or on an outer corner side of the eyelid of the eye. [Solution] In a piece of cosmetic eyelid-shaping tape 1 that includes a tape-shaped member 4 including a base material piece 2 capable of being stretched in a longitudinal direction, the base material being formed of a long and narrow synthetic resin that has elastic contractility when stretched, and an adhesive layer 3 coated on both surfaces of the base material piece, and that forms a fold 91 in an upper eyelid by using elastic contractility of the base material piece, an entire adhesive area A in the tape-shaped member used for sticking the tape-shaped member on the eyelid is a width decreasing section in which a tape width of the tape-shaped member decreases from a first end 4a side towards a second end 4b side.
