Abstract
An ECU includes a substrate and a chassis. Electronic components are mounted on a first primary surface of the substrate. The chassis includes a protruding portion that protrudes toward a position different from where the electronic components are. A height of the protruding portion is greater than a height of the electronic components, and shorter than a gap between the substrate and the heat sink. When warping occurs in the substrate and the first primary surface approaches an opposing surface of the heat sink, the protruding portion contacts the first primary surface. Accordingly, the electronic components are prevented from contacting the heat sink. Further, other electronic components may be mounted on an entire area of a second primary surface of the substrate.
