ELECTRONIC UNIT

摘要

An electronic unit includes a heat sink, a substrate, a heating component, a temperature sensor, a first interconnection, and a second interconnection. The heat sink includes a strut. The substrate is fixed to the strut of the heat sink. The heating component is mounted on the substrate to generate heat upon energization of the heating component. The temperature sensor is mounted on the substrate to detect temperature. The first interconnection is provided in a high-temperature region in which the heating component is mounted on the substrate, and is connected to the strut of the heat sink. The second interconnection is provided in a detection region in which the temperature sensor is mounted on the substrate, and is provided separately from the first interconnection. The second interconnection is connected to the strut of the heat sink and the temperature sensor.
