Patent ID: 7692277

Claim:
A lead frame for a semiconductor light-emitting device, comprising: a lead frame body; and a plurality of metal coatings which are applied to the lead frame body, wherein: a predetermined part of the lead frame is formed by extending one pair of inner leads, which are separated by a gap, toward each other in a state where extended portions of the pair of inner leads are flat and flush with each other, the predetermined part being to be enclosed with a package of the semiconductor light-emitting device; a semiconductor light-emitting element is to be mounted at a predetermined position of the predetermined part so as to straddle the extended portions; the package includes a cover made of a transparent resin and a base made of an insulating resin whose refractive index is different from a refractive index of the cover, the cover being in contact with the predetermined position; a portion of the lead frame body being in contact with the base includes a part whose outermost coating is a gold or gold-alloy coating, and another part whose outermost coating is a silver or silver-alloy coating; an outermost coating of a part of the predetermined part being in contact with the cover is the silver or silver-alloy coating, and the silver or silver-alloy coating is different from the gold or gold-alloy coating.
