PROBLEM TO BE SOLVED: To improve a ratio of non-defectives by hindering intrusion of bubbles. SOLUTION: A concave lens 1 is horizontally set. Ultraviolet curing type resin liquid 10 is dropped onto its concave face 1A. A mold 2 having a convex aspheric face 2A is set with the aspheric face upside, and such quantity of resin liquid 10 as not to drip off when the mold is turned upside down is dropped onto a center of the aspheric face 2A. The mold 2 is turned upside down and placed above the lens 1. The lens 1 and the mold 2 are made to approach each other until a tip of resin liquid 10 on the concave face of the lens 1 is brought into contact with a tip of the resin liquid 10 on the aspheric face 2A of the mold 2. A space between the lens 1 and the mold 2 is further narrowed so as to have a predetermined space, and they are irradiated by ultraviolet light 20, while sandwiching the resin liquid 10 to be cured. A resin molded layer 10A obtained by curing is made to exfoliate from an interface with the mold 2. COPYRIGHT: (C)2003,JPO |
