Abstract

PURPOSE:To prevent the pressing-out of conductive resin for fastening LED pellets by a method wherein base sections to which the LED pellets are disposed are previously protruded arranging the height of the base sections when the pellets are each disposed to a plurality of conductive base sections mounted onto an insulating substrate. CONSTITUTION:A plurality of a pair of the first and second conductive base sections 12, 13, which are mutually separated, using copper plates, etc. are formed on a surface layer section of an insulating substrate 11 consisting of alumina porcelain, etc. The height of the base sections 12 loading LED pellets 1 formed by GaP, etc. is previously made higher than all projecting sections made up to the substrate 11, arranging the height, and electrodes 2 at the one crystal sides 1a of the pellets 1 are fastened to the base sections 12 by using adhesives 14 in epoxy resin to which silver powder is contained. Thus, the adhesives 14 is not pressed out because there is step difference between the base sections 12 and the substrate 11. And electrodes 3 at the upper sections of the pellets 1 are bonded to other base sections 13 by using wires 15.
