摘要：
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.
