A method of manufacturing a composite body of a sheet-like member of an absorbent article, the method includes: holding a first sheet-like member on a holding surface of a holding section; and delivering and attaching the first sheet-like member from the holding surface to a second sheet-like member. The first sheet-like member has a section that is to be delivered first, and a section that is to be delivered subsequently during delivery to the second sheet-like member. The first sheet-like member is held on the holding surface with suction air from a plurality of holes that have been formed on the holding surface. The holding section has at least two suction chambers. A first suction chamber is in communication with holes that suck the section that is to be delivered first, and a second suction chamber is in communication with holes that suck the section that is to be delivered subsequently.
