Abstract
An object of the present invention is to provide an LED device that can achieve a large total luminance flux while also achieving a structure, using a phosphor sheet, that is compact in size and easy to produce and whose color emission is easy to manage, and a method for producing such an LED device. A semiconductor light-emitting device including a semiconductor light-emitting element which includes a transparent insulating substrate and a semiconductor layer formed on a lower surface of the transparent insulating substrate, a phosphor resin which covers a side face of the transparent insulating substrate, and which wavelength-converts a portion of light emitted from the semiconductor light-emitting element, and a phosphor sheet which covers an upper surface of the phosphor resin and is bonded to the transparent insulating substrate, wherein the phosphor sheet has a top plan shape that is identical with an outer peripheral shape of the phosphor resin, and the top plan shape of the phosphor sheet defines an overall outer plan shape of the device.
