To provide a method for manufacturing an absorbent article in which a shape of a compression part can be maintained stably, and an absorbent body can be prevented from being hardened.SOLUTION: A method for manufacturing an absorbent article 1 of the present invention includes: a supply step of supplying at least an absorbent body P3, in a gap of a pair of rolls including a first roll 30 where multiple first protrusions 32 are arranged in an outer circumferential surface and a second roll 40 where multiple second protrusions 42 are arranged in the outer circumferential surface； and a forming step of compressing the absorbent body from both sides of the thickness direction by making each of the multiple first protrusions face each of the multiple second protrusions while inserting at least the absorbent body into a space between the first roll and the second roll, and forming multiple compression parts 12. The first roll and the second roll are configured such that a projection of the first area A1 of the top 32 t of the first protrusion to a second area A2 of a top 42 t of the second protrusion may be fitted in the second area while the first protrusion and the second protrusion for forming the compression part are opposed to each other.SELECTED DRAWING: Figure 6【課題】圧搾部の形状を安定的に維持でき、かつ、吸収体が硬くなることを抑制可能な吸収性物品の製造方法を提供する。【解決手段】本吸収性物品１の製造方法は、複数の第１凸部３２が外周面に配置された第１ロール３０と、複数の第２凸部４２が外周面に配置された第２ロール４０とを備える一対のロールの隙間に、少なくとも吸収体Ｐ３を供給する供給工程と、第１ロールと第２ロールとの間に少なくとも吸収体を挿通しつつ、複数の第１凸部の各々と、複数の第２凸部の各々とが互いに対向するようにして、吸収体を厚さ方向の両側から圧搾し、複数の圧搾部１２を形成する形成工程と、を備える。第１ロール及び第２ロールは、圧搾部を形成する第１凸部と第２凸部とが互いに対向する状態において、第２凸部の頂部４２ｔの第２領域Ａ２に対する第１凸部の頂部３２ｔの第１領域Ａ１の射影が第２領域内に収まるように構成されている。【選択図】図６
