Abstract
Provided is an electric power steering apparatus which allows a reduction in apparatus size as well as in noise. A controller () includes: a metal board (), on which a bridge circuit including a plurality of semiconductor switching elements (Qto Q) for switching a current of an electric motor () is mounted; capacitors () for absorbing a ripple of the current; a control board (), on which a microcomputer () for generating a drive signal for controlling the bridge circuit is mounted; and a connection member formed by insert molding high-current conductive plates (and), through which a high current flows, and signal conductive plates (), to/from which a low-current signal is input/output, with a frame () made of an insulating resin provided in proximity to an outer periphery of the metal board (), in which the capacitors () are arranged in a row along an end surface of one side of the metal board () and are electrically connected to the high-current conductive plates ().
