Abstract
A multi-layer piezoelectric element includes: a stacked body comprising an active section, and inactive sections disposed at opposite ends in a stacking direction of the active section; an electrically-conductive bonding material disposed on a side surface of the stacked body from the active section to the inactive sections; and an external electrode plate attached, through the electrically-conductive bonding material, to the side surface of the stacked body, a spacing between a side surface of at least one of the inactive sections and the external electrode plate being wider than a spacing between a side surface of the active section and the external electrode plate, and the electrically-conductive bonding material situated between the side surface of at least one of the inactive sections and the external electrode plate being larger in thickness than the electrically-conductive bonding material situated between the side surface of the active section and the external electrode plate.
