[Problem]An object of the present invention is to provide an electric power steering apparatus that gradual-changes a steering angle control command value, an assist control command value and also a steering angle speed command value, suppresses an excessive accumulation of an integral value in a speed control by being provided a steering speed command value with a limiter, and does not give the driver an uncomfortable feeling.[Means for solving the problem]The present invention is the electric power steering apparatus that has a function to switch between an assist control mode and a steering angle control mode, wherein the steering angle control section comprises a position control section that inputs a target steering angle and an actual steering angle and outputs a first steering angle speed command value; a gradual-changing limiting section that limits an upper limiting value and a lower limiting value by gradual-changing a first steering angle speed command value corresponding to a steering angle control gradual-changing gain; a speed control section that processes a second steering angle speed command value, which is outputted from the gradual-changing limiting section, based on an actual steering angle speed and a steering angle control gradual-changing gain; and a first gradual-changing section that gradual-changes the first steering angle control command value, which is outputted from the speed control section, corresponding to a steering angle control gradual-changing gain and outputs a second steering angle control command value, further comprises a second gradual-changing section that gradual-changes a first assist control command value, which is outputted from an assist control section, with an assist control gradual-changing gain and outputs a second assist control command value, wherein a steering angle control section, and a motor current command value is generated based on the second steering angle control command value and the second assist control command value.
