A method for producing an absorbent article from a first continuous sheet and a second continuous sheet, the method comprising: a cover sheet bonding step of bonding a cover sheet to the second continuous sheet that comprises a second sheet constituting the absorbent article, connected in a machine direction, an expandable-and-shrinkable member bonding step of bonding an expandable-and-shrinkable member that is expandable and shrinkable in an expansion-and-shrink direction so that the expansion-and-shrink direction is along a widthwise direction of the first sheet, with a center section of the expandable-and-shrinkable member in the expansion-and-shrink direction in a high-expanded state and both end sections (11b, 11b) on both sides of the center section in a low-expanded state, while transporting the first continuous sheet that comprises a first sheet constituting the absorbent article, connected in the machine direction, in the machine direction; and an integral bonding step of successively bonding the first sheet and the second sheet, while transporting each of the first continuous sheet and the second continuous sheet in the machine direction, wherein the cover sheet bonding step includes a cover sheet bonding step of bonding the cover sheet at locations corresponding to the both end sections of the expandable-and-shrinkable member so that the both end sections of the expandable-and-shrinkable member are covered by the cover sheet with the first sheet and the second sheet in a bonded state, and includes a step of situating a pair of leak resistant walls extending along the machine direction and separated in the widthwise direction of the first sheet or the second sheet on the first sheet or the second sheet in such a manner that edges of the leak resistant walls in the machine direction cover the both end sections of the expandable-and-shrinkable member as the cover sheet. a cover sheet bonding step of bonding a cover sheet to the second continuous sheet that comprises a second sheet constituting the absorbent article, connected in a machine direction, an expandable-and-shrinkable member bonding step of bonding an expandable-and-shrinkable member that is expandable and shrinkable in an expansion-and-shrink direction so that the expansion-and-shrink direction is along a widthwise direction of the first sheet, with a center section of the expandable-and-shrinkable member in the expansion-and-shrink direction in a high-expanded state and both end sections (11b, 11b) on both sides of the center section in a low-expanded state, while transporting the first continuous sheet that comprises a first sheet constituting the absorbent article, connected in the machine direction, in the machine direction; and an integral bonding step of successively bonding the first sheet and the second sheet, while transporting each of the first continuous sheet and the second continuous sheet in the machine direction, wherein the cover sheet bonding step includes a cover sheet bonding step of bonding the cover sheet at locations corresponding to the both end sections of the expandable-and-shrinkable member so that the both end sections of the expandable-and-shrinkable member are covered by the cover sheet with the first sheet and the second sheet in a bonded state, and includes a step of situating a pair of leak resistant walls extending along the machine direction and separated in the widthwise direction of the first sheet or the second sheet on the first sheet or the second sheet in such a manner that edges of the leak resistant walls in the machine direction cover the both end sections of the expandable-and-shrinkable member as the cover sheet.
