A reflector that functions as a fluorescent member is formed of a transparent resin material including a fluorescent substance dispersed therein capable of emitting light by excitation of light emitted from a semiconductor light emitting element, on the bottom of the case so as to surround the semiconductor light emitting element, having an inner surface of curved surface of concave arc shape having a section extending from the height of the bottom of the case obliquely upward, in a shape that continues along substantially the entire circumference of an oval or elongated round shape, thereby achieving uniform light emission without color heterogeneity, for example, white light of high output power.
