Lead frame for optical semiconductor device and optical semiconductor device using the same

摘要

The present invention relates to a lead frame for an optical semiconductor device including: a lead frame having a first plate part and a second plate part disposed so as to oppose to the first plate part; an optical semiconductor element placed in the second plate part and electrically connected to the second plate part; a wire for electrically connecting the optical semiconductor element and the first plate part to each other; a circumferential reflector formed on the lead frame so as to surround a circumference of the optical semiconductor element; and a transparent resin for encapsulating the optical semiconductor element, filled in a recess formed by the lead frame and an inner periphery of the reflector, in which the lead frame has a contour shape substantially the same as a bottom contour shape of the inner periphery of the reflector for forming the recess.
