Abstract
An ultrasonic motor in which a voltage is applied to a piezoelectric element by using a lead board. To fabricate the motor in a simplified manner, it is so constructed that a plurality of conductive patterns on the lead board are joined to a plurality of electrodes formed on the piezoelectric element by solder or the like, the piezoelectric element and the lead board are prevented from contacting each other by bending the conductive patterns to form a gap, then a voltage is applied to the lead board, thereby realizing the drive.
