Abstract
A semiconductor element is fixed with an indium film that is formed on an electrode by plating. This permits precise control of the amount of indium applied to the electrode and thus secure fixing of the semiconductor element on the electrode To minimize loss in the light emission efficiency of the semiconductor element and variations of the hue of the light it emits, the indium film has a thickness preferably in the range from 5 to 10 &mgr;m. Using a ZnSe-based light-emitting element as the semiconductor element is more effective. To ensure secure and economical fixing of the semiconductor element on the electrode with the indium film the indium film formed on the electrode has an area preferably in the range from 1.1 to 1.5 times the area of the surface over which the semiconductor element is fixed.
