An electric actuator includes a motor, an output shaft, a detent plate, an elastic portion including a contacted portion, a first rotation sensor, a second rotation sensor, and a controller. In a case where an abnormality has occurred in the second rotation sensor, the controller executes causing the motor to rotate to cause the contacted portion to abut a first side wall portion located on one end side in the circumferential direction of a first valley portion in the detent plate, acquiring the first rotation angle when the contacted portion abuts on the first side wall portion, reversely rotating the motor to an angle, and determining that the contacted portion is stationary at the parking position.
