Standing gathers-forming sheets (162) are arranged in an absorbent article (10), and standing gathers are formed. A pair of front and rear end region bonded parts (162A, 162B), at which the front and rear end regions of the standing gathers-forming sheets (162) are bonded with a sheet disposed on the skin-contact surface side thereof, are formed on the lengthwise front and rear end regions of the standing gathers-forming sheets (162). The absorbent core (22) has a low-rigidity region and a high-rigidity region. At least the end parts of the front and rear end region bonded parts (162A, 162B) that are close to the crotch part (C) are disposed on the high-rigidity region of the absorbent core (22). The low-rigidity region comprises a block region and the high-rigidity region comprises a non-block region. The block region has a block structure comprising a plurality of high basis weight parts having a relatively high basis weight, and a low basis weight part having a relatively low basis weight. Across the entire block region, the periphery of each of the high basis weight parts is surrounded by the low basis weight part, and each high basis weight part is independent.於吸收性物品(10)中配置立體褶皺形成用片材(162)而形成有立體褶皺。於立體褶皺形成用片材(162)中,在其長度方向之前後端部區域形成有將該前後端部區域與位於肌膚抵接面側之片材接合的前後一對端部區域接合部(162A、162B)。吸收性芯體(22)具有低剛性區域及高剛性區域。端部區域接合部(162A、162B)中,其等中之至少靠近下襠部(C)之端部位於吸收性芯體(22)之高剛性區域上。低剛性區域包含塊狀區域,高剛性區域包含非塊狀區域。塊狀區域具有包含基重相對較高之複數個高基重部及基重相對較低之低基重部的塊狀構造,各高基重部之周圍係遍及其整個區域地由該低基重部包圍從而分別獨立。10‧‧‧尿布21‧‧‧正面片材22‧‧‧吸收性芯體24‧‧‧側翼161‧‧‧立體褶皺彈性構件162‧‧‧立體褶皺形成用片材162A‧‧‧端部區域接合部162B‧‧‧端部區域接合部163‧‧‧側翼彈性構件164‧‧‧彈性片材165a‧‧‧彈性構件165b‧‧‧彈性構件234a‧‧‧高基重部234b‧‧‧低基重部235‧‧‧塊狀區域236‧‧‧非塊狀區域237A‧‧‧腹側部高基重部群237B‧‧‧背側部高基重部群237C‧‧‧下襠部高基重部群A‧‧‧腹側部B‧‧‧背側部C‧‧‧下襠部CL‧‧‧度方向中心線F‧‧‧黏扣帶W‧‧‧腰部開口緣X‧‧‧寬度方向Y‧‧‧長度方向
