Provided are an electric-powered actuator and an electric braking device which are capable of reliably operating a reverse-input holding mechanism and can achieve cost savings. The electric-powered actuator includes a control device (2) including: a motor angle estimation unit (22a), and a reverse-input holding control section (24) having a function of engaging an engaging part (15) with an engaged part by controlling a solenoid (16) to set the reverse-input holding mechanism (7) into a reverse-input holding state while the electric-powered actuator (DA) is applying a load and a function of, from the reverse-input holding state, disengaging the engaging part (15) from the engaged part to set the reverse-input holding mechanism (7) into a reverse-input holding release state. The reverse-input holding control section (24) includes an engagement intermediate control function section (24a) configured to control the estimated rotation angle such that the engaged part and the engaging part (15) come into a predetermined positional relation within a certain period of time, when the engaging part (15) is brought into engagement with the engaged part and when the engaging part (15) is brought out of engagement with the engaged part.
