Abstract
A light-emitting device includes: a substrate comprising a base; a semiconductor laser element disposed on an upper surface of the base; a sealing member located above the base and fixed to the substrate, wherein the sealing member and the substrate define a sealed space in which the semiconductor laser element is located; and a lens member fixed to the sealing member by adhesive, the lens member comprising a lens section through which light emitted from the semiconductor laser element passes. A space between the sealing member and the lens member is open to an area outside the light-emitting device.
