Further, in the present invention, the gather structure composed of a large number of elastic strips disposed over the entire region of the front body and the rear body results in a wood grain arrangement as a whole.
Further, in the present invention, the elastic body groups of the front body and the back body are disposed substantially equally (equally spaced) in the front and rear at the left and right seal line portions, and each elastic body is provided at the middle part (the center line of the left and right). As it goes, it protrudes in the shape of a bulge toward the crotch part, and the degree of the protrusion gradually increases from the waist part to the leg part. Further, in the present invention, a group of elastic bodies having the same length are bridged between the left and right seal lines in the front and rear with equal tension, and each elastic body is bulged and curved toward the crotch toward the middle part. And the degree of overhang is gradually increased from the waist portion to the leg portion, so that the tension of each elastic strip is gradually increased from the waist portion to the leg portion.

By gradually changing from g to 40 g, the fit of the pants as a whole is improved and the feeling of use is improved. Further, in the present invention, the gather structure is symmetrical with respect to a center line passing through the front body and the back body in the front-rear direction, and is symmetrical with respect to the center line passing through the crotch in the left-right direction. Furthermore, in the present invention, the closest approach distance between the bulging curved portions protruding toward the crotch of each elastic body group in the front body and the back body is set to 20 mm or more. Furthermore, the full-pants type disposable diaper of the present invention has an approximately hourglass-like developed shape in which the front and rear bodies are continuous through the inseam, and the corresponding both sides of the front and rear bodies are used as seal lines to form a seal line on both sides of the inseam. The seal is formed in a complete pants shape except for the constricted part for the leg part. Further, the sheet member for a completely pants-type disposable diaper having a substantially hourglass-like developed shape of the present invention is interposed between the inner (body side) water-permeable sheet and the outer (clothing side) non-water-permeable sheet, and both sheets. It has a water absorbing member of an appropriate shape as a basic configuration.
