Abstract:
A light-emitting device includes a substrate that includes at least a pair of electrodes, an LED element electrically mounted on the substrate, a phosphor plate adhered to an upper surface of the LED element and including an upper surface and a lower surface each having an area larger than that of the upper surface of the LED element, a white resin provided on an upper surface of the substrate and seamlessly covering a peripheral side surface of the LED element and a peripheral side surface of the phosphor plate. A lower surface of the phosphor plate is adhered to the upper surface of the LED element through a transparent adhesive.
