There are provided a substrate configured to have a circuit wiring, semiconductor light emitting elements configured to be mounted on the substrate, a frame configured to be vertically provided on the substrate in an annular or oval-annular shape so as to surround the semiconductor light emitting element, and a sealing portion configured to seal an inner wall of the frame, an upper surface of the substrate inside the frame, and the semiconductor light emitting elements. The sealing portion includes a first resin portion configured to have a concave surface having at least one rotational plane having a central axis of the frame as a rotational axis, and a second resin portion configured to cover the concave surface of the first resin portion and having a convex external surface, and the sealing portion has an external surface in which an external surface of the first resin portion and an external surface of the second resin portion are integrated.
