An in-vehicle electronic control unit includes a circuit board equipped with a coil and a power supply circuit, a resin member covering the circuit board, and a metal bracket fixed to the resin member for attaching the circuit board to a vehicle. The metal bracket includes a first shield portion and a second shield portion. The first shield portion is arranged to only a part of an upper surface of the resin member so that when projected in a winding axis direction of the coil, the first shield portion overlaps at least a part of the coil. The second shield portion extends from the first shield portion in the winding axis direction of the coil and is arranged to only a part of a side surface of the resin member.

In-vehicle electronic control unit

An electronic control device includes a substrate, a plurality of component-mounted wires disposed on the substrate, a plurality of electronic components mounted on the respective component-mounted wires, a common wire coupled with each of the electronic components, an interrupt wire coupled between one of the component-mounted wires and the common wire, and a heat release portion. The interrupt wire melts in accordance with heat generated by an overcurrent. The heat release portion is attached to the common wire and is disposed at a position where a wiring distance from the interrupt wire is shorter than a wiring distance between the interrupt wire and any of the electronic components except for one of the electronic components mounted on the one of the component-mounted wires.
