To provide a controller for rotary electric machine and an electric power steering apparatus which can increases decreases an increase amount of the current of d-axis in the negative direction appropriately, and can perform the weakening magnetic flux appropriately, irrespective of increase and decrease in the rotational angle speed, without using the information on the inductance and the interlinkage flux of the rotor. A controller for rotary electric machine, in a case where the current command value of q-axis is a positive value, changes the current command value of d-axis, based on a deviation between an offset q-axis current command value obtained by subtracting the q-axis offset value of the positive value from the current command value of q-axis, and the current detection value of q-axis.
