Abstract

PURPOSE:To prevent the lowering of luminous output, and to reduce cost by a method wherein a metallic layer into which Cu is difficult to diffuse is stacked on a Cu layer at a tip of a lead wire for installing the semiconductor light-emitting element, and the exposed surface is covered with an Ag layer. CONSTITUTION:The whole surface of an Fe raw material 21 is covered with the Cu layer 22, and an Ni plating layer 23 is formed in a concave section 4, into which an LED pellet is mounted, at a nose. The layer 23 is made up where upper than a necessary section (an alternate long and short broken line) because the surface of a plating liquid shakes practically. The Ag plating layer 24 is formed so as to cover the exposed surface of the Ni layer 23. According to this constitution, the expensive Ag layer 24 is thinned and Cu ions precipitating on the surface can be decreased up to the one seventh or one tenth of conventional constitution in the metallic thin strip, and cost can be reduced.
