捨てることができるから、邪魔になることがない。In the disposable diaper according to the present invention, one of the right and left side portions of the front and rear body and the other right and left side portion are joined at a portion where they are overlapped with each other. The problem of discomfort caused by biting can be solved, and instability of the joint portion, which is observed in the case of joining via a tape fastener, can be eliminated. The part of the side coated with the pressure-sensitive adhesive is lined with release paper and has higher rigidity than the surroundings, so that the part can be quickly identified with respect to the surroundings, and the joining operation becomes easy. The release paper can be cut along the cut-out guide portion and the unnecessary portion can be discarded when worn, so that it does not become an obstacle.
