Optical component, injection molding die for optical component, and injection molding method for optical component

摘要

An optical component is configured to optically connect a light-emitting element and an optical fiber, and includes an optical surface arranged in a middle of an optical path of a light to be emitted from the light-emitting element to the optical fiber to reflect the light. The optical surface includes an optical path area configured to reflect the light and a non-optical path area other than the optical path area, and the optical path area and the non-optical path area are coplanar. The optical path area has a smooth surface, and at least a part of the non-optical path area has a rough surface which is rougher than the optical path area.
