Abstract: PURPOSE:To improve heat dissipation properties and reduce weight and cost by forming an iron nickel alloy layer and a copper layer mutually closely together in the direction where a heat radiating plate crosses the direction of surface and rear direction at right angle and setting the total sectional area of these layers to a specific ratio. CONSTITUTION:With a heat-radiating plate 4, a copper layer 13a is used as a core, the surrounding is rolled by an iron nickel alloy layer 14a, and the periphery of that layer is rolled by a copper layer 13b.
