Pants-type absorbent article

This pants-type absorbent article is provided with an absorbent main body, an exterior body, and a pair of side joining sections. The pair of side joining parts joins the ventral region and the dorsal region of the exterior body at lateral edge parts in the transverse direction orthogonal to the longitudinal direction. The side joining section has a waist end region, a leg end region, and a long seal section row in which long seal sections are arranged in the longitudinal direction and which is disposed in at least one of the end regions. Each long sealing part comprises an inner side sealing area located on the transverse inner side and an outer side sealing area located on the transverse outer side, wherein the sealing strength of the outer side sealing area is higher than that of the inner side sealing area. The degree of melting of the fibers in the outer sealing region is higher than the degree of melting of the fibers in the inner sealing region. The inner sealing region has microscopic irregularities f
