Abstract
A ratio of a length of resin flow-in to a radius of an optical component is not larger than 0.25, and gas is blown directly against a laser irradiated part radially and diagonally downward from an upside position corresponding to a center of the optical component. A laser line beam having longer sides extending in a direction along an inner wall is cast by a laser radiation device while being moved in the direction of the longer sides.
