- the diaper 10 A is formed in a pants shape having a waist opening 17 and a pair of leg openings 18, and a front waist region 14 and a rear waist region 16 facing each other, and the waist regions A crotch region 15 positioned between 14 and 16, and both end portions 19 extending laterally outside both end edges 13 a of the core 13; and a core 13 Both sides of It has both sides 20, 21, 22 extending outside the edge 13 b and extending in the vertical direction, respectively.
- the waist opening 17 and the leg opening 18 are formed by overlapping the sides 20 and 22 of the front and rear waist regions 14 and 16 in a palm-shape manner and extending vertically near the side edges 20 and 22. They are connected by a plurality of heat fusion wires 23 intermittently arranged.
- the diaper 10 A has a lower inseam area 15 than the front and rear waist areas 14 and 16 because the sides 21 of the inseam area 15 form an arc inward in the lateral direction of the diaper 1 OA. It is formed narrow. Therefore, the diaper 1OA breaks the connection between the front and rear waist regions 14 and 16, and the flat shape when deployed in the vertical direction assumes an almost hourglass shape.
- the inner surfaces of the sheets 11, 12 are bonded together with the front sheet 11 and the back sheet 12 overlapping each other. It is intermittently joined via an agent (not shown).
- a pair of tape tabs 26 extending in the lateral direction are attached to both sides 20 of the front waist region 14.
- the tape tab 26 is formed by folding a single piece of the tape tab 26 into a ⁇ shape in cross section, as shown by the two-dot chain line in FIG. Can be deployed.
