Abstract
A board of a controller of a load drive device includes: wiring layers provided on front and rear surfaces and inside thereof and ground layers provided inside thereof. Each wiring layer is divided into: a first region in which a drive circuit is provided; and a second region in which a control circuit is provided. A first ground layer including a first ground pattern for a circuit which is electrically connected to a wiring pattern of each wiring layer is divided into: a third region which overlaps with the first region in a thickness direction, and in which the first ground pattern for a power system electrically connected to the drive circuit is provided, and a fourth region which overlaps with the second region in the thickness direction, and in which the first ground pattern for a control system electrically connected to the control circuit is provided.
