The present invention provides an absorbent article in which a joining strength between sheet-shaped members is improved. A joint portion which joins a front trunk-surrounding region and a rear trunk-surrounding region of the absorbent article to each other has a first joint region arranged continuously along an outer edge and the second joint portion arranged continuously in a region closer to the outer edge than the first joint region, substantially parallel to the first joint region. The sum of the areas of the plurality of first joint portions in the first joint region is less than the sum of the areas of the second joint portions in the second joint region.

Absorbent article having joint regions

The present invention provides an absorbent article imparting superior comfort during wearing without inhibiting an absorbent property of an absorbent body, and a manufacturing method thereof. In the stretchable non-woven fabrics composed of a stretchable thermoplastic fiber and a heat-adhesive fiber having a lower melting point than that of the thermoplastic fiber which is arranged on a skin non-contacting side of a chassis, a low-stretchability portion is formed, in which the stretchability of the stretchable non-woven fabrics is lowered, at least in a portion thereof which overlaps an absorbent body in a thickness direction. The low-stretchability portion is formed by heating and pressurizing the portion of an elasticized non-woven fabric being extended.
