PROBLEM TO BE SOLVED: To provide a bonding method for an optical disk which restrains the formation of bubbles between an upper disk and a lower disk to a minimum in a series of processes in which the optical disk is manufactured. SOLUTION: The following processes are provided; a process in which a UV-curing adhesive 5 is circularly applied to the upper disk D1 and the lower disk D2 after they are mounted on a turntable 1, a process in which the upper disk D1 is turned over, a process in which the upper disk D1 is moved above the lower disk D2 by using a suction chuck 8c, a process in which the lower disk D2 is lifted and laminated on the upper disk D1 while controlling the moving speed of a suction chuck 9a and then the disk formed by the lamination is moved on a spinner 10 by a moving arm 8, a process in which the adhesive 5 is extended and developed in the lamination disk D mounted on the spinner 10 while rotating the disk D, and a process in which the lamination disk D is moved from the spinner 10 to a turntable 11 and then the disk D is irradiated with ultraviolet rays.
