A method for producing an absorbent article, comprising: a providing step of providing a semi-processed continuous body comprising semi-processed products for the absorbent article connected in a machine direction, the semi-processed product comprising a pair of protrusion sections formed protruding outward at both ends in the widthwise direction of the semi-processed product, and an expandable-and-shrinkable member that is expandable and shrinkable in an expansion-and-shrink direction and is disposed in an expanded state between the pair of protrusion sections so that the expansion-and-shrink direction is along the widthwise direction; characterised by a shrinking step of shrinking the expandable-and-shrinkable member to reduce a length in the widthwise direction at a portion including the expandable-and-shrinkable member in the semi-processed product to a length shorter than that before the shrinking, and form a plurality of wrinkles in the expandable-and-shrinkable member; a pressing step of pressing a center region in the widthwise direction of the semi-processed product, while transporting the semi-processed continuous body with the expandable-and-shrinkable member shrunk in the machine direction; and a folding step of raising, in a direction opposite from a direction of the pressing, a pair of side section regions (PA, PA) on both outer sides in the widthwise direction of the center region of the semi-processed product at a pair of folding lines (FL1, FL2) extending along the machine direction set more toward an inner side than both end sections in the widthwise direction of the expandable-and-shrinkable member, and folding each of the pair of side section regions upward above the center region, while transporting the semi-processed continuous body in the machine direction. a providing step of providing a semi-processed continuous body comprising semi-processed products for the absorbent article connected in a machine direction, the semi-processed product comprising a pair of protrusion sections formed protruding outward at both ends in the widthwise direction of the semi-processed product, and an expandable-and-shrinkable member that is expandable and shrinkable in an expansion-and-shrink direction and is disposed in an expanded state between the pair of protrusion sections so that the expansion-and-shrink direction is along the widthwise direction; characterised by a shrinking step of shrinking the expandable-and-shrinkable member to reduce a length in the widthwise direction at a portion including the expandable-and-shrinkable member in the semi-processed product to a length shorter than that before the shrinking, and form a plurality of wrinkles in the expandable-and-shrinkable member; a pressing step of pressing a center region in the widthwise direction of the semi-processed product, while transporting the semi-processed continuous body with the expandable-and-shrinkable member shrunk in the machine direction; and a folding step of raising, in a direction opposite from a direction of the pressing, a pair of side section regions (PA, PA) on both outer sides in the widthwise direction of the center region of the semi-processed product at a pair of folding lines (FL1, FL2) extending along the machine direction set more toward an inner side than both end sections in the widthwise direction of the expandable-and-shrinkable member, and folding each of the pair of side section regions upward above the center region, while transporting the semi-processed continuous body in the machine direction.
