PURPOSE:To manufacture a disk in favorable yield by adhering the disks in order toward an outside circumferential direction under a state where air is not entered, by a method wherein first and second disks are laminated by facing in the outside circumferential direction under a state where the inside diameter parts of the first and second disks may be a point contact when the center holes of the first and second disks, which are bent to make the ridgeline in the radial direction, coincide with each other. CONSTITUTION:A first disk 3A is bent slightly into a saddle form centering around a line L1 by inserting a positioning pin 12 into a center hole 7A under a state where the surface of the first disk 3A, to which an adhesive agent 8 has been applied, turns upside. Then a second disk 3B is bent slightly into the saddle form centering around a line L2 under a state where a protective film 6B turns lower side. When the positioning pin 12 is inserted into a center hole 7B so that both the diameters meet at an angle of 90 deg. under the state where the second disk 3B is bent into the saddle form, the inside diameter parts come into contact with each other under a state where they perform point contact, and registration of the center holes 7A, 7B can be performed correctly. When degrees of bends of the first and second disks 3A, 3B are reduced gradually under the state, the disks can be stuck in order from an inside circumferential part to an outside circumferential direction under the state where air is not entered. |
