PROBLEM TO BE SOLVED: To provide a method and a device for stacking an optical disk substrate, wherein a state of the oblique loading of the optical disk substrate is prevented when the optical disk substrate is loaded on a stack pole. SOLUTION: In the stacking method of an optical disk substrate 1 for loading the circular optical disk substrate 1 taken out from an injection molder, the optical disk substrate 1 is rotated in a period before it is loaded on a stack pole 2. Thus, even if the optical disk substrate 1 has uneven thickness, a state of the oblique loading thereof is prevented when it is loaded on the stack pole.
