    • PROBLEM TO BE SOLVED: To provide a piezoelectric linear ultrasonic motor which directly makes the linear movement of a mover in forward and backward directions at a precision of nm order and is higher in efficiency and longer in service life. SOLUTION: The piezoelectric linear ultrasonic motor includes a pair of half-wavelength converters 80 each comprising a plurality of piezoelectric ceramics 20 generating mechanical vibrations, a horn 10 which is positioned at a lower part of the piezoelectric ceramics 20 and augments vibration and a metal material 30 wherein the piezoelectric ceramics 20 are pressure-bonded by a bolt 40, a vibration beam 90 interlocked with the half-wavelength converters 80, a projected portion 50 which is formed at the center of the vibration beam 90 and generates elliptic mechanical displacement in accordance with different two-phase high-frequency AC electric fields that are applied to the half- wavelength converters 80, and a mover 70 that is put into contact with the projected portion 50 and is linearly driven by a frictional force generated between the projected portion 50 and the mover.
