Abstract
A light-emitting device includes: a base having a depressed portion upwardly opening, the depressed portion having a bottom surface, surrounding surfaces and at least one placement surface disposed at a position higher than the bottom surface; at least one semiconductor laser element mounted on or above the bottom surface; and a wavelength conversion member enclosed in the depressed portion to convert a wavelength of light from the at least one semiconductor laser element, the wavelength conversion member having a lower surface disposed on the at least one placement surface and a circumferential edge partly surrounded by the surrounding surfaces.
