ABSTRACT:
A light emitting module10is provided with a semiconductor light emitting device21, a semiconductor light receiving device22, a mount member20on which the semiconductor light emitting device21and semiconductor light receiving device22are mounted, a lens32, and a lens holding member30for holding the lens32. Part of light emitted by the semiconductor light emitting device21is reflected by a reflecting film32cprovided on a first surface32aof the lens32to enter the semiconductor light receiving device22. Therefore, the semiconductor light receiving device22can receive forward light from the semiconductor light emitting device21, without using a half mirror.
