An electric linear motion actuator includes an electric motor, a motion conversion mechanism for converting the torque of the electric motor to the linear driving force of an outer ring member, a load sensor, and a motor control device. The motor control device is configured to control the electric current applied to the electric motor such that the torque of the electric motor increases until the pressing force detected by the load sensor exceeds a target value, and then the torque of the electric motor decreases until the pressing force detected by the load sensor reaches the target value.
