摘要：
A motor drive control device for electric power steering includes: a switching element for supplying current to a motor; a smoothing capacitor for reducing ripple current due to the switching element; a control board on which a drive circuit for controlling the switching element and a control circuit capacitor are mounted; a control signal line for supplying a control signal from the control board to the switching element; an electric connection member electrically connecting the switching element and the smoothing capacitor; and a heatsink portion in which the switching element is arranged in an embedded manner, wherein the electric connection member is arranged between the switching element and the control board, and the control circuit capacitor and the smoothing capacitor are arranged in a space between the electric connection member and the control board.
