An object of the present invention is to provide an electric actuator having a structure capable of reducing an external force or impact acting on a screw shaft when a piston rod is at a stretched position. An electric actuator (1) includes a first port (6), a second port (7), and a cylinder chamber connecting passage (9), the first port (6) is formed on an inner face of a rod-side cylinder chamber (5a) of a cylinder body (2), the second port (7) is formed on an inner face of a head-side cylinder chamber (5b) of the cylinder body (2), the cylinder chamber connecting passage (9) connects the first port (6) and the second port (7). In the electric actuator (1), a piston part (4a) of a piston rod (4) closes the first port (6) when the piston rod (4) advances.
