PROBLEM TO BE SOLVED: To make targets to be irradiated which are arranged at positions adjacent to and distant from the surface of a mounting board generate lights with the identical semiconductor light emitting element. SOLUTION: An aperture part of a cover 8 composed of opaque synthetic resin of a semiconductor light emitting element 1 is filled with translucent synthetic resin 7, and a spherical curved surface 7a converging an output light of a semiconductor light emitting chip 5 on one side surface is formed. When a target to be irradiated is set at a position of X on an axial line Z perpendicular to a mounting board 9, a light generating focus is formed at the position of X by mounting the semiconductor light emitting element 1 on a position of (P) of the mounting board 9. When a target to be irradiated is set at a position of Y on the same axial line Z which is distant from the surface of the mounting board 9, a light generating focus is formed at a position of Y by mounting the semiconductor light emitting element 1 on a position of (Q) of the mounting board 9.
