Abstract:
A light-emitting device includes a light-emitting element including first and second main surface, and a first lateral surface; a wavelength conversion member including a third main surface, a fourth main surface, and second lateral surfaces; a light-transmissive adhesive member; and a first light-reflective member containing a light-reflective first filler, covering the first lateral surface provided with the light-transmissive adhesive member, and including third lateral surfaces being peripheral surfaces of the first light-reflective member. In a cross-section in a direction perpendicular to the second main surface, a distance between the third lateral surfaces is smaller than a distance between the second lateral surfaces at a fourth main surface side. Each of the second lateral surfaces of the wavelength conversion member includes a first inclined surface in a region adjacent to the third main surface. The wavelength conversion member includes light-reflective particles located on the first inclined surface.
