Abstract
A light-emitting device includes: a substrate including a base and a side wall; a plurality of semiconductor laser elements arrayed in a first direction on an upper surface of the base; a sealing member 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 array disposed above the sealing member, the lens array including a plurality of lens sections arrayed in the first direction. In the lens array, a maximum outer diameter of each lens sections is 1.25 times or more than an inter-vertex distance between adjacent ones of the lens sections in the first direction.
