A piezoelectric/electrostrictive linear motor is provided. A movable shaft is coupled to a unimorph or bimorph, which is made by attaching a piezoelectric or electrostrictive substrate to an elastic body, so that a movable body provided with respect to the movable shaft is linearly moved along the movable shaft by the vibration or movement of the piezoelectric or electrostrictive substrate.
