摘要:
Provided is a light-emitting device of which a resin frame serving as a dam of a sealing resin is not readily deformed. The light-emitting device includes: a planar lead frame configured from first and second metal portions which are spaced apart from each other with an insulating resin interposed therebetween; light-emitting elements mounted on the first metal portion and electrically connected by wires to the first and second metal portions; a first resin frame disposed on the lead frame so as to enclose the light-emitting elements; a sealing resin containing a phosphor for converting the wavelength of light emitted from the light-emitting elements, the sealing resin being filled into a region on the lead frame enclosed by the first resin frame to seal the light-emitting elements; and a second resin frame being harder than the first resin frame and covering an outer surface of the first resin frame at an outer edge of the lead frame.
