Abstract:
1. An electronic control device comprising: a substrate; a coupling object mounted on the substrate; an interrupt wire configured to melt in accordance with heat generated by an overcurrent so as to interrupt a coupling with the coupling object, the interrupt wire having a first side end and a second side end facing to each other; a first etching resist region disposed adjacent to the first side end of the interrupt wire; a second etching resist region disposed adjacent to the second side end of the interrupt wire; and a connection wire coupling the interrupt wire to the coupling object, wherein a distance between the first etching resist region and the first side end is equal to a distance between the second etching resist region and the second side end, and wherein a wire width of the connection wire increases toward the coupling object in an arc manner.
