Patent ID: 8334587

Claim:
A semiconductor light emitting device, comprising: a first lead having an upper surface, the first lead extending in a direction; a second lead provided apart from the first lead; a semiconductor light emitting element provided on and physically contacting the upper surface of the first lead; a wiring electrically connecting the semiconductor light emitting element and the second lead; and a first resin provided at least on and contacting the first lead and on and contacting the second lead, and being optically transparent to light from the semiconductor light emitting element, the first resin provided such that a portion of the first lead extends generally horizontally out from the resin, wherein a part of the first lead contacting the first resin is substantially symmetric about a vertical line passing through the semiconductor light emitting element in a cross-sectional view cut along a plane, the plane passing through the semiconductor light emitting element and being parallel with the direction in which the first lead extends from the first resin, wherein the first lead has an opening, and wherein a gap from the first lead to the second lead along the direction to which the first lead is extended is substantially equal to the width of the opening of the first lead in the cross-sectional view cut along a plane, the plane passing the semiconductor light emitting element and being parallel with a direction to which the first lead is extended.
