PROBLEM TO BE SOLVED: To facilitate adjustment of the perimeters of leg cylinder parts.SOLUTION: In the manufacturing method of an absorbent article, a right half part of a crotch member 2 is joined on a first sheet member 51, with a first upper layer part 511 superposed on a first lower layer part 512. Further, a second sheet member 52 is joined on a left half part of the crotch member 2, with a second upper layer 521 superposed on a second lower part 522. Subsequently, a first leg connection sheet 43 and a second leg connection sheet 44 are joined with the first sheet member 51 and the second sheet member 52, with a width-directional central part superposed on a first non-continuation part 515 and a second non-continuation part 525. Then, the first sheet member 51 and the second sheet member 52 are spread, and the first sheet member 51 and the second sheet member 52 are joined together at width-directional both side edges. This method can facilitate adjustment of the perimeters of the leg cylinder parts in an outer wrapping sheet of the absorbent article 1.【課題】脚筒部の周長を容易に調節する。【解決手段】吸収性物品の製造方法では、第１上層部５１１と第１下層部５１２とが重ねられた状態で、第１シート部材５１上に股下部材２の右半分の部位が接合される。また、第２上層部５２１と第２下層部５２２とが重ねられた状態で、股下部材２の左半分の部位上に第２シート部材５２が接合される。続いて、第１脚部接続シート４３および第２脚部接続シート４４が、幅方向の中央部が第１非連続部５１５および第２非連続部５２５に重ねられた状態で、第１シート部材５１および第２シート部材５２接合される。そして、第１シート部材５１および第２シート部材５２が展開され、幅方向の両側縁部にて第１シート部材５１と第２シート部材５２とが接合される。これにより、吸収性物品１の外装シートにおいて、脚筒部の周長を容易に調節することができる。【選択図】図８
