Abstract:
1. A semiconductor light emitting device comprising: embedding resin; a first lead having a first inner lead section embedded in the embedding resin and a first outer lead section protruding from one side face of the embedding resin; a second lead having a second inner lead section embedded in the embedding resin and a second outer lead section protruding from a side face opposed to the one side face of the embedding resin; a semiconductor light emitting chip mounted on a portion of the first inner lead section exposed in a recess provided on an upper face of the embedding resin; and a wire connecting the semiconductor light emitting chip with the second lead, the first inner lead section and the second inner lead section being physically separate, the first and second inner lead sections and the first and second outer lead sections each having a substantially coplanar rear face, and at least a part of the rear face of the first inner lead section and at least a part of the rear face of the second inner lead section being not covered with the embedding resin but being exposed, wherein the first inner lead section has a first thickened portion having a thickness greater than that of a tip of the first outer lead section, the first outer lead section has a second thickened portion having a thickness greater than that of a tip thereof, and the first and second thickened portions are continuously provided.
