In an electric rotating machine apparatus according to the present disclosure, there is adopted a structure in which an extending portion of a control circuit board on which a power module for supplying electric power to windings and a driving circuit for the power module are mounted passes through an external-connection opening portion of an electromagnetic shield and then is connected with connectors. A filter circuit 11 is mounted on the extending portion of the control circuit board so as to secure noise-removal capability. Because a conventional dedicated wiring board for mounting the filter circuit thereon is not required, the foregoing structure can contribute to downsizing and cost reduction. In addition, the foregoing structure can contribute to downsizing and cost reduction of an electric power steering apparatus equipped with the electric rotating machine apparatus according to the present disclosure.
