ABSTRACT:
An electronic control device includes a power supply circuit, electronic circuits, a ground wiring pattern, and a common ground wiring pattern formed in a multi-layered substrate. The ground wiring pattern is dedicated for the power supply circuit and the common ground wiring pattern is provided for all electronic circuits. Even when an electrical potential of the ground wiring pattern varies due to a switching operation of a switching component included in the power supply circuit, the common ground wiring pattern is not affected.
