An electronic controller used in electric power steering includes a first substrate including a switching circuit to supply a drive signal to an electric motor and at least one electrolytic capacitor to smooth a power-supply voltage that is a source of the drive signal. The at least one electrolytic capacitor is mounted on a first surface (a bottom surface of a frame), the switching circuit and the at least one electrolytic capacitor are mounted on a surface of the first substrate that is different from the first surface, and the at least one electrolytic capacitor and the first substrate are arranged above and below the switching circuit, respectively.
