PROBLEM TO BE SOLVED: To easily peel both upper/lower protrusions by one step by pulling any one of the upper/lower protrusions, while improving a degree of freedom of locking direction and position of the upper/lower protrusions of a fastening tape.SOLUTION: A fastening tape 5 is configured that a tip end of a body part 5e is bifurcated to be formed into an upper protrusion 51 and a lower protrusion 52, and the upper protrusion 51 and the lower protrusion 52 include hook materials 9 formed corresponding to an outer face of an abdominal-side part. A shape of an edge 60 from an upper-part peel start position 61 to a lower-part peel start position 63 linearly extends from the upper-part peel start position 61 to a root part 5f side, is curved just once at a part closest to the root part 5f side, and linearly reaches the lower-part peel start position 63 .
