Abstract
Provided is an electric linear motion actuator that enables size reduction and cost reduction while increasing the instantaneous output of an electric motor. A control device () of the electric linear motion actuator includes: a motor driver () configured to control power supplied to a coil () of an electric motor (); a power storage unit () connected to a power supply device () and the motor driver (); a current flow direction restriction unit () disposed between the power supply device () and the power storage unit (), which causes current to pass only in a direction in which power is supplied from the power supply device (); and a step-up unit () configured to step up voltage of the power supply device () and provide the stepped-up voltage to the power storage unit ().
