Abstract
The present invention is aimed to prevent occurrence of COD and rapid degradation of light output in semiconductor laser devices. The semiconductor laser device includes a semiconductor laser elementA and a support member. The semiconductor laser elementincludes a first electrode, a substrate, and a semiconductor structurehaving an emitting facet and a reflecting facet, a second electrode, and a pad, in this order. The semiconductor laser elementA is connected to a support memberat its padside via a connecting member. The emitting-side end portion of the second electrodeis spaced apart from the emitting facet of the semiconductor structure, and the emitting-side end portion of the padis located at an outer side than the emitting-side end portion the second electrode
