<p>The present invention is a method of production comprising manufacturing a plastic optical component having a flange section on the outer periphery of an optical function section by injection molding using a stationary mold and a movable mold. A space for a gate for packing with a resin and a space for forming the flange section are both provided solely to the movable mold. Within the space for forming the flange section, the gate is arranged at a portion corresponding to a range that extends from a side surface of the flange section in the thickness direction of the flange section and reaches a part of a flange surface.</p> |
