摘要： In a dot pattern, both sufficient strength during the use of a diaper and the ease of tearing can be achieved, while inhibiting sticking of fiber waste of a non-woven fabric in the sealing device. The problems can be solved by the underpants-type disposable diaper characterized by a side seal section 13 is formed in a dot pattern in which a plurality of rows of dot-shaped welded parts 13s, 13b, disposed with intervals in a vertical direction, are disposed in a transverse direction, and non-welded parts 13n, disposed all over in the transverse direction, are disposed on both sides of each welded part 13s, 13b, in the vertical direction; the side seal section 13 has at least partly in the vertical direction a non-densely welded region LD and a densely welded region HD; and each welded part 13b in the densely welded region HD is larger in area than each welded part 13s in the non-densely welded region LD.

摘要翻译： 在点状图案中，可以在抑制密封装置中的无纺布的纤维废料粘附的同时，实现尿布的使用时的充分强度和易撕裂性。 这些问题可以通过一种侧密封部分13形成的内裤型一次性尿布来形成，其中沿着垂直方向间隔设置多个点状焊接部分13s，13b的点阵图形是 沿横向方向设置，并且在横向上全部设置的非焊接部13n沿垂直方向设置在每个焊接部13s，13b的两侧; 侧密封部13至少部分地在垂直方向上具有非密集焊接区域LD和密集焊接区域HD; 密集焊接区域HD中的每个焊接部分13b的面积大于非密集焊接区域LD中的每个焊接部分13s。
