PROBLEM TO BE SOLVED: To provide a disposable diaper excelling in leakage preventiveness of urine and excrement and hardly causing an uncomfortable feeling or the like due to excrement sticking to the skin.SOLUTION: The disposable diaper 1 includes an absorber 4 including a longitudinally long absorbent core 40, and has an abdominal side part A, a crotch part C and a back side part B. The absorbent core 40 has a high basis weight part 41 at the width direction center part of the crotch part C, and low basis weight parts 42 lower in basis weight than the high basis weight part 41, on both sides of the high basis weight part 41. The high basis weight part 41 has a central bending guide part 43 formed of a slit, a groove or a fiberless part extending in the longitudinal direction of the absorbent core 40, and each of the low basis weight parts 42 has a side bending guide part 44 formed of a fiberless part. The central bending guide part 43 extends from the end position of the side bending guide part 44 on the abdominal side part A side in the longitudinal direction of the absorbent core 40, and the side bending guide part 44 extends from the end position of the central bending guide part 43 on the back side part B side in the longitudinal direction of the absorbent core 40.COPYRIGHT: (C)2012,JPO&INPIT【課題】尿及び大便の漏れ防止性に優れており、大便が肌に密着することによる不快感等も生じ難い使い捨ておむつを提供すること。【解決手段】縦長の吸収性コア40を含む吸収体4を具備し、腹側部A、股下部C及び背側部Bを有する使い捨ておむつ1であり、吸収性コア40は、股下部Cにおける幅方向中央部に高坪量部41を有し、高坪量部41の両側に該高坪量部41より低坪量の低坪量部42を有しており、高坪量部41に、吸収性コア40の長手方向に延びるスリット、溝又は非積繊部からなる中央折曲誘導部43を有し、低坪量部42それぞれに、非積繊部からなる側部折曲誘導部44を有しており、吸収性コア40の長手方向の腹側部A側においては、中央折曲誘導部43が側部折曲誘導部44の端部位置より延出し、吸収性コア40の長手方向における背側部B側においては、側部折曲誘導部44が中央折曲誘導部43の端部位置より延出している。【選択図】図2
