Description

Here, if the engagement sheet 92 does not face each other, the engagement sheet 92 contacts the other part of the fastening tape 90 in a state where the fastening tape 90 is folded. When the fastening tape 90 is formed from a material that easily engages with the engagement sheet 92, for example, a nonwoven fabric, the engagement sheet 92 may be difficult to pull out by engaging the other part of the fastening tape 90. is there. In the above embodiment, since the engagement sheet 92 faces each other in a state where the fastening tape 90 is folded, a part or all of the engagement surface of the engagement sheet 92 is in contact with the other part of the fastening tape 90. It has been made difficult. Thereby, since the fall of the drawability of the fastening tape 90 can be suppressed, it becomes possible to obtain a favorable feeling of use. Specifically, the fastening tape 90 can be easily pulled out only by pulling the free end portion 93 sideways along the width direction W. The frictional force when the fastening tape 90 is developed while the engaging sheets 92 rub against each other is sufficiently smaller than the frictional force when the fastening tape 90 is pulled out with the engaging sheet 92 engaged with the nonwoven fabric. On the other hand, since the fibers are exposed on the surface of the nonwoven fabric, when the engagement sheet is engaged with the nonwoven fabric, the engagement surface of the engagement sheet is caught by the nonwoven fabric fibers during the pulling operation of the fastening tape 90, The drawability of the fastening tape 90 is reduced.
