PROBLEM TO BE SOLVED: To mold a composite type optical element which has a circular resin layer the center of which is the center of a backing without being affected by positional dislocation of an energy curing type resin discharged on the surface of the backing, the circularity of the layer, etc. SOLUTION: A mold 4 is brought down, the molding surface of the mold 4 is contacted with an energy curing type resin 2 discharged on the surface of a backing 1, and the movement of the mold 4 is stopped before the resin layer spreads out to a desired thickness or diameter. After that, the backing 1 is rotated around the optical axis 3 of the backing 3 and corrected so that the resin 2 has the same outside diameter around the optical axis of the backing 1. The mold 34 is again brought down to spread the resin to form the resin layer having a desired thickness and diameter. |
