PURPOSE:To miniaturize the title device, and to improve light-emitting luminance by a method wherein independent three leads are adopted from the beginning, the mutual intervals of these leads are reduced as much as possible while the nose surfaces of the leads are formed in approximately the same surface as the surface of a resin base and inserting and fixing the leads to the resin base. CONSTITUTION:Leads 21-23 consisting of three conductors are inserted and fastened to a resin base 20 in such a manner that one end surfaces of the leads and the surface of the resin base 20 shape approximately the same surface while intervals among each lead 21-23 are reduced as much as possible. Light- emitting elements 24, 25 are fitted to the end surfaces of two adjacent leads 21, 22. A bonding wire 26 is spanned between one light-emitting element 24 and the end surface of the lead 22 for the other light-emitting element 25. A bonding wire 27 is bridged between the other light-emitting element 25 and the end surface of the residual lead 23. |
