Abstract: 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.
