PROBLEM TO BE SOLVED: To easily peel both upper/lower projections by one step by just picking any one of the upper/lower projections, while improving flexibility of a locking direction and position of the upper/lower projections of a fastening tape.SOLUTION: A fastening tape 5 includes: an upper projection 51 and a lower projection 52 formed by dividing a tip end side of a body part 5e into two and hook materials 9 for an outer surface of an abdominal part, provided at the upper projection 51 and the lower projection 52 respectively. A shape of an edge 60 heading from an upper-part peel sart position 61 to a lower-part peel start position 63 is so formed as to linearly head from the upper-part peel sart position 61 to a root nearest part 5f side, bend just once at the root nearest part 5f side, and linearly reach the lower-part peel start position 63.SELECTED DRAWING: Figure 8
