    Abstract: An improvement is achieved in the heat dissipation property of an electronic device including power transistors. A semiconductor module includes first and second packages included in an inverter circuit. In the first package, a semiconductor chip having a high-side power transistor is embedded. In the second package, a semiconductor chip having a low-side power transistor is embedded. At the both wide surfaces of the first and second packages, first metal electrodes electrically coupled to respective collector electrodes of the power transistors and second metal electrodes electrically coupled to respective emitter electrodes of the power transistors are exposed. To the first and second metal electrodes of the first and second packages, four respective bus bar plates having areas larger than those of the first and second metal electrodes are joined.

    Abstract: An electronic device includes: a substrate having an upper surface (front surface) on which a semiconductor chip is mounted, and a lower surface (back surface) opposite to the upper surface; and a housing (case) fixed to the substrate through an adhesive material. The housing has through-holes each formed on one short side and the other short side in an X direction. The substrate is disposed between the through-holes. A part of the upper surface of the substrate is fixed so as to face a part of a stepped surface formed at a height different from that of a lower surface of the housing. Further, an interval (distance) between a part (stepped surface) extending along a short side of the housing in the stepped surface and the upper surface of the substrate is larger than an interval (distance) between a part (stepped surface) extending along a long side of the housing in the stepped surface and the upper surface of the substrate.
