Abstract
A semiconductor laser device has a semiconductor laser element, light receiving element, lead frame, and package. The semiconductor laser element is an element for emitting a laser beam. The light receiving element is a chip-shaped element which receives a monitoring laser beam emitted from the semiconductor laser element. The semiconductor laser element and the light receiving element are mounted on the lead frame. The package surrounds the semiconductor laser element and the light receiving element, and has a light reflecting surface on at least a portion of its inner surface.
