Abstract: An absorbent article has front and back surface sheets, and an absorbent body disposed within the front surface sheet and back surface sheet laminate. The absorbent article is further provided with a stretchable waist member disposed within the laminate in a manner enabling stretching in the width direction, and a pair of stretchable side members formed on the peripheral edge of the laminate in a manner enabling stretching in the width direction. One member and the other member of the pair of stretchable side members are formed, respectively, on one end and the other end of the laminate in the width direction. The stretchable waist member overlaps with each of the pair of stretchable side members in the lengthwise direction, is disposed further on the non-skin side than the absorbent body in the thickness direction, and overlaps with the absorbent body in the thickness direction but is not joined thereto.

Abstract: An absorbent article has front and back surface sheets, and an absorbent body disposed within the front surface sheet and back surface sheet laminate. The absorbent article is further provided with a stretchable waist member disposed within the laminate in a manner enabling stretching in the width direction. The stretchable waist member is disposed between the absorbent body and the front surface sheet in the thickness direction and is joined to the front surface sheet. A portion of the stretchable waist member overlaps with and touches the absorbent body in the thickness direction but is not joined thereto, and the portion of the stretchable waist member that does not overlap with the absorbent body in the thickness direction is joined to the back surface sheet.

Abstract: An absorbent article includes an absorbent main body, side flaps, leakage barriers, and an elastic member joined in between the side flaps in the absorbent main body, and stretchable and shrinkable in a width direction. Each leakage barrier includes a standing portion in which an outer side in the width direction is a fixed end, and an inner side in the width direction is a free end, and a supporting portion which is adjacent to one end portion in a longitudinal direction of the standing portion and overlaps with the elastic member in a thickness direction. The supporting portion is fixed to the absorbent main body by the heat welding portion. Each side flap is folded to the inner side in the width direction at a position of a folding line which passes through the supporting portion and extends along the longitudinal direction in a plan view.

Abstract: An absorbent article includes the absorbent main body, side flaps, leakage barriers, and an elastic member which is joined in between the side flaps, and is stretchable and shrinkable in the width direction. Each of the leakage barriers includes a standing portion in which the outer side in the width direction is fixed, and the inner side in the width direction is free, and a supporting portion adjacent to one end portion in the longitudinal direction of the standing portion and overlaps the elastic member in the thickness direction. The supporting portion includes an inner side portion which is positioned on the inner side in the width direction and is not fixed to the absorbent main body, and an outer side portion which is positioned on the outer side in the width direction and is fixed to the absorbent main body by the heat welding portion.

Abstract: An absorbent article includes an absorbent body that includes an absorber and a pair of side flaps that extend outward from both ends of the absorbent body in a width direction. The absorbent article has a dorsal side and an abdominal side in a longitudinal direction. The pair of side flaps is disposed on the dorsal side of the absorbent body. Each of the pair of side flaps includes an engaging member. Each of the pair of side flaps is joined to the absorbent article further toward a skin side in the thickness direction than the absorbent body. The engaging member includes a first edge of the abdominal side and a second edge of the dorsal side. In the longitudinal direction, a dorsal side end of the absorber is disposed further toward the dorsal side than a first imaginary line that connects the first edges.
