Abstract

PURPOSE:To prevent the degradation in the quality of a lens by forming a lens pattern of an ionization radiation setting resin to one face of a base plate having ionization radiation transmittability. CONSTITUTION:The base plate 1 having the ionization radiation transmittability is placed in the resin pool of the ionization radiation setting resin 2 and while the ionization radiation setting resin 2 is leveled off by means of press roll 4 via said base plate 1, the base plate 1 is laminated to the ionization radiation setting resin 2. The base plate 1 is then to laminated that only the end part on the roll 4 side comes into contact with a mold 3. The base plate 1 and the mold 3 are then pressurized and laminated by the rolls 4 from above the plate and below the mold to push out the air bubbles entering the resin inside and the valleys of the lens pattern shape of the mold. Furthermore, the ionization radiation setting resin 2 is cured by projecting ionization radiations thereon. The intrusion of the air bubbles into the lens part of the molded lens sheet is thereby obviated.
