PROBLEM TO BE SOLVED: To provide a heat sink for an LED lamp capable of simplifying a component configuration and reducing the manufacturing cost by surely achieving weight saving and without separately requiring a component for mounting an LED substrate.SOLUTION: A heat sink A for an LED lamp formed of a metal plate material B is composed of a heat sink body part 1 and a pedestal part 2 for LED substrate mount which bulges from the heat sink body part 1 to the surface side. The heat sink body part 1 and the pedestal part 2 are integrally formed by coining processing. A backing material 4 may be laminated on the rear side of the pedestal part 2. |
