摘要： There is provided an injection mold for molding an optical component including an optical surface, a non-optical surface separated from the optical surface, and a rib provided to an edge portion of the optical surface, and longer in a direction parallel to the optical surface than in a direction perpendicular to the optical surface. The mold includes a transfer piece including a transfer surface that molds the optical surface and a movable cavity piece including a non-transfer surface that molds at least a portion of the non-optical surface. The transfer surface and the non-transfer surface define a cavity to be filled with resin. The movable cavity piece is moved away from the resin during a process of cooling the resin. At least a portion of the non-transfer surface is located closer to the rib than a boundary between the transfer surface and the rib.
