摘要： A disposable undergarment 1 is configured, in a state where a ventral member 2 and a dorsal member 3 are separated from each other and expanded, such that a left half of a crotch side edge 10 of the ventral member 2 has a same shape as a shape of a right half of a crotch side edge 11 of the dorsal member 3, a right half of the crotch side edge 10 of the ventral member 2 has a same shape as a shape of a left half of the crotch side edge 11 of the dorsal member 3, the crotch side edge 10 and the crotch side edge 11 are symmetrical about a center line C1, a left recessed line 10b and a right recessed line 10d of the crotch side edge 10 respectively have recessed shapes being closest to a waist side edge 7 at bottom portions 10f and 10g located more toward left and right end portions 2a and 2b than the center line C1, and a left protruding line 11b and a right protruding line 11d of the crotch side edge 11 respectively have protruding shapes being farthest away from a waist side edge 8 at top portions 11f and 11g located more toward the center line C1 than left and right end portions 3a and 3b.

摘要： Provided is a disposable undergarment that has a short rise length, does not excessively compress the waist of a wearer, and achieves a stable wearing position. A disposable undergarment (1) includes a ventral member (2) and a dorsal member (3) that are bonded to each other at both bonded portions (5a, 5b), a crotch member (4) that is bonded to and bridges between both center portions (2c, 3c) of the ventral member (2) and the dorsal member (3), a waist opening (6), left and right leg openings (9a, 9b), and a first elastic member (13) that extends upward toward an upper edge (7) from lower portions of the bonded portions (5a, 5b) of the ventral member (2) to a center in a waist-around direction. The disposable undergarment (1) has a shape widening from the waist opening (6) toward the left and the right leg opening (9a, 9b) on a lower side. The upper edge (7) of the ventral member (2) has a center portion (7a) disposed lower than an upper edge (8) of the dorsal member (3).

摘要： Provided is an absorbent pad that is easy to attach to and position on a wearing article. An absorbent pad 1 with a longitudinal direction as a front-back direction of a wearer includes: a hook member 8 having a length in the front-back direction of 20 mm or more and 50 mm or less and a width in the left-right direction of 10 mm or more and 20 mm or less, the hook member 8 comprising a collection of hook pieces that are detachably hooked on a wearing article; and a hook member fixing region having a length in the front-back direction of 20 mm or more and 50 mm or less and a width in the left-right direction of more than 30 mm and less than 70 mm, and in which a plurality of the hook members 8 are fixed parallel at intervals of less than 50 mm in the left-right direction of the absorbent pad 1; the hook member fixing region is a region obtained by projecting each center region in the left-right direction of both a front end portion and a back end portion of an absorber 2,3 onto a wear-facing surface 5d.

摘要： The present invention reduces the extension stress of an absorbent article to make it easy to stretch, improves the air permeability, and increase the maximum elongation. Provided is an absorbent article (1) comprising a stretchable region, wherein the stretchable region of the absorbent article (1) is made of an elastic sheet in which a first non-stretchable sheet (21), an elastic film (23) and a second non-stretchable sheet (22) are laminated in this order. The elastic sheet is provided with a plurality of joining-opening sections (51-55) that are constituted by joints (51a-55a) to join the first non-stretchable sheet (21) and the second non-stretchable sheet (22) and openings (51b-55b) to be generated in the elastic film (23) by forming the joints (51a-55a). The joints (51a-55a) are formed by joining the first non-stretchable sheet (21) and the second non-stretchable sheet (22) in a state where the elastic film (23) is extended in a stretchable direction of the elastic region. Some or all of the joining-opening sections (51-55) form adjacent joining-opening sections (50A, 50B) constituted by a plurality of the joining-opening sections (51-55) which are close to each other.
