Abstract
An electric power-steering control device has a substrate, a heat-generating component, and a heat-storing body. The heat-generating component is disposed on one surface of the substrate and generates heat when activated. The heat-storing body is capable of storing the heat from the heat-generating components. The heat-storing body has a main body having a rectangular plate shape and disposed on the one surface of the substrate. The heat-storing body has a notch section or a recess section.
