Abstract
PURPOSE:To prevent the generation of dust by burrs by using a mold embedded with soft materials having the low adhesiveness to a resin in the inside edge and/or outside edge part of a base material. CONSTITUTION:The soft materials 6, 7 having the low adhesiveness to the UV curing resin to be used for forming guide grooves are provided to a projecting shape to the inside edge and outside edge of a photoresist 10. A metallic film 5b is formed thereon and the mold is obtd. by stripping the film 5b from the photoresist. The mold is set to a central shaft 3 and after the curable resin is coated thereon, the base material 1 is imposed on the mold. The resin 4 is cured after positioning with a jig 2. A jig 8 is thereafter inserted between the resin 4 and the soft materials 6, 7 to part the molding from the mold. Since the adhesiveness between the curable resin and the soft materials is low, the molding is easily parted from the mold and the chipping off of the burrs is decreased; in addition, the generation of dust is lessened. The resin 6 is soft and is not damaged by the jig 8.
