To suppress a top sheet from floating from an absorber when compressing the absorber including a high basis weight part and a low basis weight part, and the top sheet, in a manufacturing method of an absorbent article.SOLUTION: A manufacturing method of an absorbent article includes: a step of supplying a laminate of a top sheet 2 and an absorber 4 to between a first roll 151 and a second roll 152 including projections so as to make the top sheet face the first roll； and a step of compressing the laminate by the projection 31, forming a first high compression part 21b and a first low compression part 22b in a position corresponding to a high basis weight part HB, and forming a second high compression part 21a and a second low compression part 22a in a position corresponding to a low basis weight part LB. The projection has a high basis weight projection including a first high compression projection portion 41b and a first low compression projection portion 42b, and a low basis weight projection including a second high compression projection portion 41a and a second low compression projection portion 42a. A difference between a degree of compression in the second high compression projection, and a degree of compression in the second low compression projection is smaller than a difference between a degree of compression in the first high compression projection, and a degree of compression in the first low compression projection.SELECTED DRAWING: Figure 6【課題】吸収性物品の製造方法にて、高坪量部及び低坪量部を含む吸収体と表面シートとの圧搾の際、表面シートが吸収体から浮くことを抑制する。【解決手段】凸部を含む第１ロール１５１と第２ロール１５２の間に、表面シート２と吸収体４の積層体を、表面シートが第１ロールに面するよう供給する工程と、凸部３１で積層体を圧搾し、高坪量部ＨＢに対応する位置に第１高圧搾部２１ｂと第１低圧搾部２２ｂを形成し、低坪量部ＬＢに対応する位置に第２高圧搾部２１ａと第２低圧搾部２２ａを形成する工程を備える。凸部は、第１高圧搾用凸部分４１ｂと第１低圧搾用凸部分４２ｂを含む高坪量用凸部と、第２高圧搾用凸部分４１ａと第２低圧搾用凸部分４２ａを含む低坪量用凸部を備える。第２高圧搾用凸部分での圧搾の程度と第２低圧搾用凸部分での圧搾の程度との差は、第１高圧搾用凸部分での圧搾の程度と第１低圧搾用凸部分での圧搾の程度との差より小さい。【選択図】図６
