PROBLEM TO BE SOLVED: To provide a motor-driven direct-acting actuator and an electric brake device in which instantaneous output of an electric motor can be improved, while reducing the size and the cost.SOLUTION: A controller 2 of a motor-driven direct-acting actuator includes a motor driver 24 for controlling the power supplied to the coil 4b of an electric motor 4, power storage means 21 connected between a power supply device 3 and the motor driver 24, and electrification direction control means 20 provided between the power supply device 3 and the power storage means 21, and limiting the current flowing from the power storage means 21 to the power supply device 3. Furthermore, the controller 2 includes step-up means 19 for stepping up the voltage of the power supply device 3 and outputting to the power storage means 21.SELECTED DRAWING: Figure 2
