To provide a controller for rotary electric machine and an electric power steering apparatus which can set a control gain which is used for controlling the d-axis current command value based on the q-axis current deviation between the current command value of q-axis and the current detection value of q-axis, considering the response of the current of q-axis. A controller for rotary electric machine (10) changes the current command value of d-axis (Ido), based on a value obtained by multiplying a proportional gain (Kpid) to a q-axis current deviation (ΔIq_err) which is a deviation between the current command value of q-axis (Iqo) and the current detection value of q-axis (Iqs); and changes the proportional gain (Kpid) in inverse proportion to the rotational angle speed (ω).
