摘要： An apparatus for molding optical components of a small size and high precision is provided with good transferability and a reduced production cycle. This apparatus includes a plurality of runners arranged in a pattern allowing multi-cavity molding for molding plastic lenses each having an outer diameter of 2 mm to 12 mm and surface roughness Ra of 20 nm or less. The projected area of the entire runner is determined within a range of 1 cm2 to 12 cm2. The runners are arranged to extend around a sprue in directions perpendicular to an outer surface of the base molds. The pattern of the runners extending from the junction with the sprue to each shape transfer section is configured in two intersecting directions. A cavity is of a rectangular outer shape when seen from a pressure contact surface side.
