An electric power steering device (1), comprises an electric motor (15) which is supplied with power from a power supply device (70) to generate a predetermined steering assistance force for a steered wheel (FWl, FW2), and an assistance control device (30) which controls the amount (las) of electrical power supplied to the electric motor (15), according to the steering state of a steering wheel (11). The assistance control device (30) detects the power supply voltage of the power supply device (70). The assistance control device (30) controls the electrical current (las) supplied to the electric motor (15), so as to maintain the power supply voltage greater than or equal to a set voltage (VO) which is set in advance.
