摘要： PROBLEM TO BE SOLVED: To provide a method to accurately and efficiently produce a molding using a low-viscosity liquid resin because there have been faults in which in the molding of a liquid resin, the liquid resin penetrates into a clearance between components by a capillary phenomenon and is cured, ejection is not carried out well, so that a molding is not obtained, or demolding becomes troublesome, and a long time is required for a cycle.
SOLUTION: In order to seal the liquid resin, a resin molding 3 having elasticity is used as part of a cavity and pressure-contacted with lens pieces 1 and 2 of metal to prevent the leakage of the liquid resin 6. In order to suppress curing contraction, a resin supplement opening is formed, and the curing of its part is delayed.
