PROBLEM TO BE SOLVED: To provide an absorbent article capable of effectively preventing an outer casing from being stripped from an absorbent main body without impairing its breathability and softness.SOLUTION: An underpants-type absorbent article has a deformation induction region in which an absorbent core is oriented along the longitudinal direction Y. A ventral exterior body 2A and a dorsal exterior body 2B, and an absorbent main body 3 are bonded in multiple ventral bonding sections which extend along the width direction X and are discontinuous in the longitudinal direction Y. A crotch sheet 6 and a back sheet are bonded in a crotch bonding section which extends in the longitudinal direction Y and is discontinuous in the width direction X. The length in the longitudinal direction Y of a region SGwhere a bonding region KSand a bonding region MS overlap is 50% or less than the length in the longitudinal direction Y of the bonding region KS. The length in the longitudinal direction Y of a region SGwhere a bonding region KSand the bonding region MS overlap is 50% or less than the length in the longitudinal direction Y of the bonding region KS.【課題】柔らかさや通気性を損なうことなく、外装体が吸収性本体から剥離することを効果的に防止できる吸収性物品を提供する。【解決手段】吸収コアが長手方向Ｙに沿う変形誘導領域を有している。腹側外装体２Ａ及び背側外装体２Ｂと吸収性本体３との接合が、幅方向Ｘに延び、長手方向Ｙに間欠している複数条の腹側接合部において行われる。股下シート６と裏面シートとの接合が、長手方向Ｙに延び、かつ幅方向Ｘに間欠している股下接合部において行われる。接合領域ＫＳFと接合領域ＭＳとが重なる領域ＳＧFの長手方向Ｙの長さが、接合領域ＫＳFの長手方向Ｙの長さの５０％以下である。接合領域ＫＳBと接合領域ＭＳとが重なる領域ＳＧBの長手方向Ｙの長さが、接合領域ＫＳBの長手方向Ｙの長さの５０％以下である。【選択図】図８
