In the above, the adhesive is not applied between the top sheet 2 and the back sheet 3, so that the elastic members 51, 61, 71 at the joint portion 8 are formed by the top sheet 2 and the back sheet 3. It is in a non-extended state without being fixed to any of them. The non-stretched state can also be achieved by applying a release agent to a portion of the top sheet and the back sheet where the bonding section is formed, for example, and performing a release treatment. Here, the “non-stretched state” refers to a state in which each elastic member is not stretched and the stretch ratio is close to 0%, specifically, a state of 0 to 20%.
The “stretch rate” is the ratio of the length that has been increased by stretching to the natural length. For example, when a 10 cm long piece is stretched to 20 cm, the stretch rate is 100%.

いに優れ、装着感に優れたものである。The pants-type disposable diaper of the present embodiment can be used in the same manner as a commonly known pants-type disposable diaper. In the case of a conventional disposable diaper, contraction of the elastic member at the joint portion causes the joint portion to become stiff, resulting in a significant reduction in texture. The members 51, 61, 71 are sandwiched and fixed to the top sheet and the back sheet via an adhesive in an extended state, respectively. However, in the joint portion 8, each elastic member 51, 61, 71 is in a non-extended state. Therefore, the joint 8 has no adverse effect due to the shrinkage, and does not cause such a decrease in texture. Therefore, the disposable diaper according to the present embodiment has an excellent texture and an excellent wearing feeling.

る。In the present embodiment, the member disposing step O is performed by repeating the above-described continuum 2 'of the top sheet, the continuum 3' of the back sheet, the continuum 51 'of the waist elastic member, and the waist circumference. An adhesive is intermittently applied to each member of the continuum 61 ′ of the elastic member and the continuum 71 ′ of the leg elastic member so that the adhesive is not applied to a portion of the diaper where the joint is formed. Then, it is performed by arranging each member. In this case, as a method of intermittently applying the adhesive, a known method can be used without any particular limitation. When each elastic member is set in the non-stretched state by the peeling treatment, the intermittent adhesive is not applied, for example, the continuous body 2 ′ of the top sheet is used.
The member disposing step O can be performed by applying a release agent to a portion of the continuous body 3 ′ of the back sheet where the above-mentioned joint is formed. Next, after performing the folding step S and the opening forming step P, the bonding section forming step Q is performed to form a bonding section. Further, after that, in the above cutting step R, the continuous body of each elastic member is adhered in order to cut the stretched elastic member at a portion where the elastic member is not adhered (a portion forming a joint in each disposable diaper). In the non-joined portion, each of the elastic members 51, 61, 71 contracts and becomes a non-extended state,
A joint is formed to provide an individual disposable diaper.
