A light emitting module includes a semiconductor light source, a first lead with a bonding pad to which the light source is attached, and a second lead spaced from the first lead in a first direction contained in the plane of the first die bonding pad. The second lead includes a wire bonding pad connected to the light source via a wire. The module also includes a case formed with a space elongated in the first direction for accommodating the light source. The first lead includes an extension extending from the first die bonding pad, and a mounting terminal connected to the extension. The extension extends in a second direction that is perpendicular to the first direction and contained in the plane of the first die bonding pad. The mounting terminal extends perpendicularly to the second direction. The extension overlaps the light source in the first direction.
