摘要： The present invention aims at providing a disposable diaper having excellent maintainability of a surface space and capable of being easily produced. It is characterized in that a lower layer absorbent body (23B) has, at least at center of a crotch portion (C2) in a width direction, an elongated lower layer through section (60) piercing in a thickness direction and extending in a front-back direction; an upper layer absorbent body (23A) has an upper layer through section (50) piercing in the thickness direction at least within a range corresponding to the lower layer through section (60) in the front-back direction, the upper layer through section (50) has an elongated middle section (51) extending in the front-back direction so as to be located above the lower layer through section (60), and extending sections (52) which extend, in the width direction, from both sides of a back side position of the middle section (51), and a side edge of the extending section (52) has a shape in which at least a part of the front side thereof is located further outside in the width direction toward the back side.
