An absorbent article having a longitudinal direction and a widthwise direction crossing the longitudinal direction, said absorbent article comprising:

• a topsheet provided at a side configured to come into contact with a skin of a wearer;
• a backsheet provided at a side configured to be separated from the wearer's skin;
• and
• an absorber provided between the topsheet and the backsheet, wherein both side portions of the absorber in the widthwise direction are folded,
• wherein the absorber comprises:
• a body unit having a constricted portion constricted inwardly in the widthwise direction when viewed from a plan view of the absorber;
• and
• a pair of extension units extending from the body unit outwardly in the widthwise direction in a state in which the both side portions have been unfolded,
• wherein the constricted portion is formed in a center region in the longitudinal direction, and
• wherein each of the extension units comprises:
• an inner region provided at the constricted portion and continuous to the body unit;
• and
• an outer region continuous to the inner region and positioned outside of the inner region in the widthwise direction,
• wherein the outer region is folded toward the inner region at a side of the topsheet, and a length of the inner region along the longitudinal direction is shorter than a length of the outer region along the longitudinal direction, and
• wherein a width of the absorber from an outer edge of one of the extension units to an outer edge of the other extension unit is wider than a width of the absorber in an end portion in the longitudinal direction in a state in which the both side portions have been unfolded.
