PROBLEM TO BE SOLVED: To more reliably raise three-dimensional gathers.SOLUTION: An absorbent article 1 includes a nearly sheet-shaped body part 2 extending in a longitudinal direction and a pair of side sheets 3 arranged on both side parts of the body part 2 and extending in the longitudinal direction. Each of the side sheets 3 is provided with: a side sheet body 31 where a base part 311 is fixed to the body part 2 with one end part in a width direction vertical to the longitudinal direction as the base part 311 a free end part elastic member 32 which is bonded at a free end part 313 along the longitudinal direction and contracts in the longitudinal direction with an end part of the side sheet body 31 on the opposite side to the base part 311 in a width direction as the free end part 313 and an auxiliary area elastic member 33 which is bonded to an auxiliary area 314 away from the free end part elastic member 32 toward the base part 311 in the side sheet body 31 and contracts at least in the width direction. In the absorbent article 1, an area between the free end part elastic member 32 and the auxiliary area 314 can be more reliably raised.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】立体ギャザーをより確実に起立させる。【解決手段】吸収性物品1は、長手方向に延びる略シート状の本体部2と、本体部2の両側部上に配置され、長手方向に延びる一対のサイドシート3とを備える。各サイドシート3は、長手方向に垂直な幅方向における一方の端部を基部311として、基部311が本体部2に固定されるサイドシート本体31と、幅方向において基部311とは反対側におけるサイドシート本体31の端部を自由端部313として、自由端部313において長手方向に沿って接合され、長手方向に収縮する自由端部弾性部材32と、サイドシート本体31において、自由端部弾性部材32から基部311に向かって離れた補助領域314に接合され、少なくとも幅方向に収縮する補助領域弾性部材33とを備える。吸収性物品1では、自由端部弾性部材32と補助領域314との間の領域をより確実に起立させることができる。【選択図】図1
