ABSTRACT:
A semiconductor light-emitting device has a pair of leads placed in parallel, a light-emitting element on the upper end of one lead, a bonding wire for electrically connecting the semiconductor light-emitting element of the upper end of another lead, and an envelope formed from a light-transmitting resin for sealing the semiconductor light-emitting element, the bonding wire, and the upper end of the leads, provided with a non-circular lateral cross-sectional surface structure with a long axis and a short axis. In the device, when observed along a direction in which the plurality of light-emitting devices are mounted on a same lead frame, a curvature of the lateral direction of said envelope is smaller than a curvature of the vertical direction of said envelope.
