PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a composite optical element capable of suppressing an optical accuracy from lowering and fluctuating caused by the misalignment of the centers of an optical substrate and a formed plane. SOLUTION: The method for manufacturing the composite optical element comprises a process for adjusting an axis according to an axis position of a formed plane 111a using an optical axis detecting means 112 capable of detecting an axis of a measuring plane form from a detecting distance along the optical axis corresponding to the measuring plane form of a measuring object, and with an auxiliary measuring plane 115a capable of being positioned with regard to the formed plane and of detecting the axis with the optical axis detecting means. In the process for adjusting an axis, the axis adjustment is performed on the basis of the result of detecting the axis of the auxiliary measuring plane, which is conducted in such a state that the optical axis detecting means is disposed at a position capable of detecting an optical plane La. The detection of the axis of the auxiliary measuring plane is conducted in such a state that the formed plane is nearer to a forming position k than when detecting the axis of the formed plane.
