Abstract:
1. An electronic control device comprising: 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 disposed on the substrate and coupled with each of the electronic components; an interrupt wire coupled between one of the component-mounted wires and the common wire, the interrupt wire configured to melt in accordance with heat generated by an overcurrent so as to interrupt a connection between the one of the component-mounted wires and the common wire via the interrupt wire; and a heat release portion attached to the common wire and made of the same material as the common wire, the heat release portion 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.
