Abstract: An electric actuator for rotating a driven shaft is provided, and includes: a motor unit, a speed reducer, a circuit board and an output section. A motor shaft of the motor unit and an output shaft of the output section are disposed apart from each other in a radial direction of the motor shaft. A rotor main body of the motor unit is fixed to a portion on the other side of the motor shaft in the axial direction. The output shaft has a cylindrical shape extending in the axial direction of the motor shaft and having an opening section on the other side in the axial direction. The driven shaft is inserted and connected to the output shaft via the opening section from the other side in the axial direction. The output shaft is disposed at a position overlapping the rotor main body in the radial direction.
