Original Abstract Submitted
A light-emitting device includes a base, a first metal member, a second metal member, a semiconductor laser element, and a lid body. The base has an upper surface and a lower surface. The first metal member is disposed on the upper surface of the base and has a thickness in a vertical direction in a range from 50 μm to 150 μm. The second metal member is disposed on the upper surface of the base and has a thickness in the vertical direction identical to the thickness of the first metal member. The second metal member is spaced apart from the first metal member in a top view and surrounds the first metal member. The semiconductor laser element is disposed on the first metal member. The lid body is bonded to the base via the second metal member.
