PURPOSE:To readily manufacture an illuminator by directly arranging a light emitting element in an element containing recess to conduct it with a metal substrate, thereby eliminating the necessity of laminating an insulating layer and a conductive layer in the recess. CONSTITUTION:A plurality of element containing recesses 3 are formed at a suitable interval longitudinally on a metal substrate 1 made of a conductive material, and the surface except the recesses 3 is covered with an insulating layer 4. A common conductive layer 5 is so formed on the layer 4 as to extend longitudinally of the substrate 1. A light emitting element 2 is made of a semiconductor chip, directly disposed fixedly at the center on the bottom of each recess 3 to conduct with the substrate 1, and electrically connected via gold wirings 7 as leads with the conductive layer 10 of the element. |
