Abstract:
A light-emitting device includes a base member, conductor wiring on an upper surface of the base member, a reflective member covering the upper surfaces of the base member and the conductor wiring and having apertures to expose part of the upper surface of the base member and part of the upper surface of the conductor wiring, a plurality of light sources bonded to the part of the upper surface of the conductor wiring located in the apertures with bonding members, and a reflector that is disposed on the reflective member and includes a plurality of first surrounding portions and a plurality of second surrounding portions surrounding the first surrounding portions, which respectively surround the light sources in a plan view. Each surrounding portion has inclined lateral surfaces that widen in an upward direction. An aperture in each second surrounding portion is smaller than an aperture in each first surrounding portion in the plan view.
