Patent ID: 7094619

Claim:
A method of manufacturing a semiconductor light-emitting device, comprising: mounting a light-emitting element on one of leads that are arranged side by side in a longitudinal direction of a lead frame; and sealing part of the leads and the light-emitting element with light-transmitting resin, the sealing part of the leads and the light-emitting element with light-transmitting resin including forming the light-transmitting resin such that the shape of a horizontal section of the light-transmitting resin perpendicular to a longitudinal direction of the leads has a long axis and a short axis and is noncircular and axially symmetrical with respect to each of the long and short axes, such that the short axis is parallel to the longitudinal direction of the lead frame, and such that the shape of a light emitting face on a vertical section of the light-transmitting resin parallel to the longitudinal direction of the lead frame and parallel to the longitudinal direction of the leads is substantially a U-shape.
