Abstract

An absorbent article including an absorbent main body including an absorbent core; and a pair of leak-proof walls. The pair of leak-proof walls are on respective widthwise side portions of the absorbent main body. Each of the leak-proof walls is capable of standing on a skin side in the thickness direction. The absorbent core includes a low-basis-weight portion in a widthwise central portion. The low-basis-weight portion has a basis weight of the absorbent core smaller than the basis weight in a surrounding portion. A joined part is formed by joining a surface of the skin-side portion and a surface of the non-skin-side portion, the surfaces facing to each other. The joined part is provided inside a distal end of the leak-proof wall and outside the low-basis-weight portion in the width direction. A part of the joined part and a part of the low-basis-weight portion overlap in the longitudinal direction.
