Abstract: A method for producing an underpants-type disposable diaper including a stretchable region stretchable at least in one direction in an outer body. The stretchable region is formed by stacking an elastic film between a first sheet layer composed of a nonwoven fabric and a second sheet layer composed of a nonwoven fabric. When the elastic film is stretched in the stretching and contracting direction, the first sheet layer and the second sheet layer are joined via through holes formed in the elastic film at a large number of sheet bond portions arranged at intervals in each of a stretching and contracting direction and a direction orthogonal thereto, and in the sheet bond portions, the first sheet layer and the second sheet layer (20B) are joined at least by a melted and solidified material of the elastic film among the first sheet layer and the second sheet layer.

Abstract: Both high air permeability and high peeling strength are achieved.

Abstract: [Technical problem] A disposable diaper having excellent performances in both the absorbable capacity and the absorption rate, is provided.

Abstract: An absorbent of a disposable diaper is formed of a lower layer absorbent and an upper layer absorbent, wherein a pair of left and right slits is extended in a front-rear direction region including a crotch portion, wherein the left slit and the right slit are spaced apart in a width direction, wherein a top sheet includes a depressed portion that falls into the slits, and wherein, in at least a region located between the slits in the top sheet, a large number of convex portions is arranged in a zigzag manner while being spaced apart by an interval, and the interval between the adjacent convex portions in the width direction is shorter than each of sizes in the width direction of the convex portions located at the front side and at a rear side of a part of the interval.

Abstract: An absorbent article (200) includes an absorbent body (23) provided at a front and rear direction range including a crotch portion (C2), and a topsheet (22) that covers a top side of the absorbent body (23), wherein a slit (40) with a predetermined width is formed in the absorbent body (23) at least at the crotch portion (C2) to extend in a front and rear direction, and wherein the topsheet (22) includes a fall-in portion (30) that is fallen in the slit (40) of the absorbent body (23), and convex portions (31) are provided at least at a part of the fall-in portion (30).

Abstract: Upon issuance of an attribute certificate, an attribute authority apparatus makes a determination policy available. The determination policy includes information designating at least one item to be checked by a service provider apparatus for determination to be made to verify the attribute certificate, and a criterion for the determination. The determination policy may be recorded in the attribute certificate, or released to public, or made available by issuing a determination policy certificate released to public. Information for obtaining the determination policy certificate may be recorded in or outside the attribute certificate and furnished to the service provider apparatus. In order to verify an attribute certificate transmitted from a user terminal, a service provider apparatus obtains the determination policy, and determines whether data in the at least one item designated in the determination policy fulfill the criterion recorded in the determination policy.
