Abstract

An electronic control device includes a substrate, a plurality of component-mounted wires, a plurality of electronic components, a common wire, an interrupt wire and a protective layer. The component-mounted wires and the common wire are disposed on the substrate. The electronic components are mounted on the respective component-mounted wires and are coupled with the common wire. The interrupt wire is coupled between one component-mounted wire and the common wire, and is configured to melt in accordance with heat generated by an overcurrent to interrupt a coupling between the component-mounted wire and the common wire. The protective layer covers a surface of the substrate including the interrupt wire and defines an opening portion so that at least a portion of the interrupt wire is exposed.

First claim

What is claimed is:

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…
