Abstract: A light-emitting device includes a semiconductor laser element, a wavelength conversion member, and a package. The wavelength conversion member includes a wavelength conversion portion and a reflective portion. The wavelength conversion portion includes a light incident surface and a light-emitting surface. The package includes a disposition region. The wavelength conversion member is disposed at a position away in a first direction from a position at which the semiconductor laser element is disposed. The light-emitting surface has a shape that, in a plan view perpendicular to the light-emitting surface, has a first region decreasing in width in a second direction perpendicular to the first direction from the side closest to the semiconductor laser element toward the first direction.
