A device for manufacturing a composite body of a continuous sheet-like member by attaching and handing over a retained workpiece to a continuous sheet-like member, at a workpiece hand over position including a rotating body that rotates about a rotating shaft, a workpiece retaining portion supported by the rotating body in a state where a retaining surface that retains the workpiece faces outward in a direction of radius of gyration of the rotating body, a workpiece hand over mechanism that is positioned to accord with the workpiece hand over position along a direction of rotation of the rotating body, and that hands over the workpiece from the retaining surface to the continuous sheet-like member when the retaining surface passes the workpiece hand over position, wherein the workpiece hand over mechanism has a roller that comes into contact with the continuous sheet-like member to transport the continuous sheet-like member, and a pushing mechanism that is capable of pushing out an outer circumferential face of the roller inward along the direction of radius of gyration to push the continuous sheet-like member against the workpiece, and the pushing mechanism changes an amount by which the outer circumferential face is pushed out in conjunction with a location, of the retaining surface along the direction of radius of gyration, at the workpiece hand over position.
