Original Abstract Submitted
A light-emitting device includes a package and a semiconductor laser element. The package includes a frame portion, a lid portion, a base having a thickness in a range from 100 μm to 500 μm, and a first metal member arranged on upper or lower surface of the base, the first metal member having a thickness in a range from 10 μm to 150 μm. The base includes an insulating member having upper and lower surfaces respectively defining the upper and lower surfaces of the base. The insulating member defines a first through hole extending from the upper surface to the lower surface of the insulating member. A first conductive member is arranged in the first through hole. The first metal member covers the first through hole. The semiconductor laser element is electrically connected to the first conductive member and the first metal member.
