<P>PROBLEM TO BE SOLVED: To provide a piezoelectric actuator, a lens driving device and a photographing device which are hard to be broken against an impact such as drops or the like. <P>SOLUTION: The piezoelectric actuator comprises a piezoelectric body which is deformed with voltage applied, a deformer equipped with an electrode in contact to the piezoelectric body, and an impact absorber in contact to at least a part of the piezoelectric body and constituted of an impact absorbing substance. Normally, most of the piezoelectric actuators are constituted of fragile piezoelectric bodies including ceramic or the like. This piezoelectric actuator can absorb the impacts applied by drops or the like with the impact absorbing part, with a reduced chance of broken piezoelectric actuators. <P>COPYRIGHT: (C)2007,JPO&INPIT |
