THREE-DIMENSIONAL STACKED PIEZOELEMENT, AND PIEZOELECTRIC ACTUATOR HAVING SUCH A STACKED PIEZOELEMENT

摘要

A three-dimensional stacked piezoelement (11 , 21 , 31 , 41 , 51 , 61) is made such that at least one face of the stacked piezoelement (12, 22, 32, 42, 52, 62) is made at right angles to layer planes (8a) of the stack, so that at least sections of said face are not parallel to a stack direction of the piezoelement.
