Abstract

PURPOSE:To improve the productivity by inserting and placing the electronic circuit body having lead terminals in a U-shaped metal case in which a plurality of fins are formed, filling the metal case with a resin, and providing a plurality of pores in the metal case. CONSTITUTION:A U-shaped metal case 6 formed by extrusion molding and opened in both ends and the bottom thereof is integrally provided with plurality of radiator fins 6a in the external surface and at one side and the upper surface thereof so that those fins are parallel with the extrusion direction at the time of extrusion molding time. In this metal case 6, an electronic circuit body 1 is inserted and placed so that the lead terminals 5 are outwardly projecting from the bottom opening of the metal case 6. Further, a plurality of pores 9 are provided in the thick part of the wall forming the U-shape of the metal case 6 for serving to enhance the heat dissipation effect. Accordingly, an electronic circuit device can be obtained with high productivity, and since the thick part of the U-shaped wall of the metal case is provided with a plurality of pores 9, the heat dissipation effect can be enhanced.
