Abstract: A cover nonwoven fabric covers a back surface of an inner member from between a front side outer member and the inner member to between a back side outer member and the inner member. In this cover nonwoven fabric, a large number of holes are provided at intervals. The holes penetrate the front surface and back surface from between the front side outer member and the inner member to between the back side outer member and the inner member. The front side outer member and the back side outer member have, at least at portions overlapping with the cover nonwoven fabric and not having any elastic member, a total luminous transmittance of 50% or more.

Abstract: An underpants-type disposable diaper has a display sheet containing a resin film between an inner member and at least one of a front side outer member and a back side outer member. A cover nonwoven fabric is provided with a plurality of holes having intervals and penetrating a front and a back is interposed from at least a crotch side edge of an outer member overlapping the display sheet to a side of a waist opening between the display sheet and a liquid impervious sheet. An internal surface and an external surface of the cover nonwoven fabric are bonded to facing surfaces, respectively, through a hot melt adhesive. Compatibility between prevention of deterioration of appearance of the display sheet and prevention of a decrease in air permeability is achieved.

Abstract: A flow of an excretion liquid into a side pocket is accomplished with a simple structure using an imperforated sheet. A side pocket extending in a front-back direction LD is disposed in an absorbent article on a lateral side of an absorber. The side pocket is surrounded by a side cover portion reaching the back surface side of the absorber from above a side of a top sheet via an upper portion, an outer side, and a lower portion of the side pocket. A portion located above the side of the top sheet in the side cover portion includes a non-bonded portion not bonded to the top sheet and a bonded portion located on both front and back sides of the non-bonded portion. A gap between the side cover portion and the top sheet in the non-bonded portion is open above the top sheet and toward the side pocket.

Abstract: An underpants-type disposable diaper has outer members that separately or integrally configures a front body and a back body. An inner member is attached to the outer members from the front body to the back body. The outer members have a waist extended section that extends to a side of the waist opening of an edge of the inner member on a waist side. The underpants-type disposable diaper further has a display sheet containing a liquid impervious resin film on an outer side of the inner member in a region in which the outer members and the inner member overlap with each other in at least one of the front body and the back body, in which the display sheet extends from a region overlapping the inner member into the waist extended section.

Abstract: A cover nonwoven fabric covers a back surface of an inner member from between a front side outer member and the inner member to between a back side outer member and the inner member. The cover nonwoven fabric extends from a back surface side of a base portion of one side gather to a back surface side of a base portion of the other side gather. The cover nonwoven fabric has holes penetrating the front and back surfaces at intervals from between the front side outer and inner members to between the back side outer and inner members. The side edges of the cover nonwoven fabric are located at the positions same as the side edges of the narrowest part of the absorber in the width direction or on the center side in the width direction with respect to the side edges of the narrowest part.
