Problem to be solved: to provide a disposable diaper in which the absorption core is disposed along the absorption core along the absorption core, while the absorption core is deformed along the body of the body, while the absorbent core is disposed along the absorption core.The disposable diaper (10) has an absorption core (31) disposed at least in the crotch area (S3).In the absorption core of the hip region, there are formed a pair of low weight portions 33 extending in the longitudinal direction and spaced apart in the width direction.The absorption core is provided with a high rigidity portion including a high rigidity portion (72) and a front high rigidity portion (73) after the rigidity is higher than the surrounding region.The high rigidity portion extends between the front and rear edges of the inner edge of the low weight portion, and the outer extension line (33el) extending from the front edge edge in the outer edge of the low thickness portion to the front and rear direction.Diagram【課題】身体の股間に沿うように吸収コアを変形させつつ、着用者の股間以外の部位に対しても吸収コアを沿わせて配置し、漏れを抑制できる使い捨ておむつを提供する。【解決手段】使い捨ておむつ(10)は、少なくとも股下域(S3)に配置された吸収コア(31)を有する。股下域の吸収コアには、前後方向に延び、かつ幅方向に間隔を空けて配置された一対の低坪量部(33)が形成されている。吸収コアには、周囲の領域よりも剛性が高い後高剛性部(72)及び前高剛性部(73)を含む高剛性部が設けられている。高剛性部は、低坪量部の内側縁における前後方向の端縁から前後方向に延びる内側延長線(33IL)と、低坪量部の外側縁における前後方向の端縁から前後方向に延びる外側延長線(33EL)と、に跨がっている。【選択図】図１
