Abstract
To implement a piezoelectric actuator which can actuate a large object, such as an imaging element, in a predetermined direction at high power without involvement of rotational displacement; which can ensure a large amount of actuation; which is suitable for miniaturization and weight reduction; and which is advantageous in terms of mechanical durability and manufacturing cost. A piezoelectric actuator having a well-balanced mechanical structure is obtained by means of stacking a plurality of cross units, in each of which a pair of bimorph piezoelectric elements (andand) are crossed in the form of the letter X, into two layers (an even number of layers), and fixing the thus-stacked cross units. An imaging elementis stably supported by means of two movable ends (C-C-) provided at the extremity of the piezoelectric actuator.
