<P>PROBLEM TO BE SOLVED: To provide an ultrasonic motor and an electronic apparatus with the ultrasonic motor, capable of realizing low-voltage driving, size and cost reductions and high output using laminated piezoelectric elements. <P>SOLUTION: This ultrasonic motor is provided with a vibrating body formed by stacking a plurality of piezoelectric elements 9a, 9b, 9c and drives a moving body 7 coming into contact with the vibrating body. Internal electrodes 10a, 10b and 10c, 10d provided on the interfaces of the plurality of piezoelectric elements 9a, 9b, 9c have the same shape and external electrodes 11a, 11b, 11c, 11d, 11e which shorts the internal electrodes 10a, 10b, 10c, 10d. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
