    摘要： Durability and lifetime of a resin sealed electronic device is improved by reducing thermal stresses acting on the power element and the parts mounting on the board. A power element (1) of which the protective film on the power element is coated with a polyimide group resin at manufacturing the element is used, and a metallic heat sink (3) of which the reverse side surface (3a) (portion of mounting on a board) is not plated is used. Further, a linear expansion coefficient of the molding resin is within a range of 3x10 -6 /°C to 17x10 -6 /°C. The durability and the lifetime of the resin sealed electronic device is improved, because the thermal stresses are reduced by balancing linear expansion coefficients of the parts.
