PROBLEM TO BE SOLVED: To reduce the number of component parts in the radiator of an electronic component, and to simplify structure for reducing manufacturing costs. SOLUTION: The radiator of the electronic component comprises a cooling fin 12 where a number of fins 11 are formed on the upper surface of a metallic plane plate section 10 at specific intervals, and a metallic base plate 16 where a plurality of bottom-expanded recesses 15 are formed on the upper surface of a plane section 14 at specific intervals. In the radiator, a portion at the plane plate section 10 between the fins 11 corresponding to the bottom-expanded recess 15 is pressed by a press die 18, a projection 13 formed on the rear of the plane plate section 10 is forced and fitted into the bottom-expanded recess 15, and the cooling fin 12 and the base plate 16 are assembled for fixation. |
