Abstract
A multilayer-type piezoelectric actuator having a multilayer piezoelectric unit which is capable of enduring the extension of contraction thereof to prevent the disconnection of external electrodes. The multilayer piezoelectric unit ( ) includes a plurality of piezoelectric plates ( ) of a piezoelectric material and a plurality of internal electrodes ( ) of a conductive material arranged in alternate layers. The external electrodes ( ) are arranged on the side surfaces ( ), respectively, of the multilayer piezoelectric unit ( ) and electrically connected to a plurality of the internal electrodes ( ). The external electrodes ( ) are each configured of an electrode base ( ) arranged in contact with a corresponding side surface ( ) of the multilayer piezoelectric unit ( ), a tabular metal net conductor ( ) arranged on the electrode base ( ), and a plurality of conductive adhesives ( ) for partially bonding the electrode base ( ) and the tabular metal net conductor ( ). Adjacent ones of the conductive adhesives ( ) have a portion mutually superposed in the direction parallel to the piezoelectric plates ( ).
