To provide a controller for a rotary electric machine and an electric power steering apparatus which can suppress the error increase of the rotational angle due to the high frequency noise component included in the current detection value, while reducing the AC component error included in the sensor detection value of rotational angle, at high rotational speed. A controller (10) for a rotary electric machine estimates an estimation actual angle deviation (Δθe) which is a deviation of the rotational angle for control (θc) with respect to the true rotational angle; calculates a detection angle deviation (Δθd) which is a deviation of the rotational angle for control (θc) with respect to the detection value of rotational angle (θd); calculates a control angle deviation (Δθc) by dividing internally between the estimation actual angle deviation (Δθe) and the detection angle deviation (Δθd) ; calculates a rotational angle for control (θc) by performing feedback control so that the control angle deviation (Δθc) approaches 0; and makes the ratio (Ke) of the estimation actual angle deviation higher than the ratio (Kd) of the detection angle deviation, when the rotational speed is higher than a speed threshold value.
