Abstract
A control device for an electrically operated power steering system includes: a power substrate comprising a plurality of switching elements, that converts DC electrical current to AC electrical current by switching operation of the plurality of switching elements; an output terminal for transmitting the AC electrical current to an electric motor that generates steering torque; a conductor for electrically connecting the power substrate to the output terminal; a metallic chassis that holds the power substrate and the conductor, and supports the output terminal; and a metallic cover that faces the output terminal, and that is connected to the metallic chassis.
