Abstract:
Provided is a light emitting device with improved light extracting efficiency and further higher heat releasing performance. A light emitting device includes a planar lead frame having a first lead and a second lead, and includes a light emitting element mounted on the first lead, a resin frame surrounding a periphery of the light emitting element, a first sealing resin filled in the inner side of the resin frame and sealing the light emitting element, and a second sealing resin covering the resin frame and the first sealing resin. Lower end of inner surface of the resin frame is arranged only on the first lead, and at an outside of the resin frame, and the second resin member covers at least a part of the first lead and the second lead. Of the back-surface of the first lead, a region directly under the blight emitting element is exposed.
