Claim:
1. A unit of piezoelectric element comprising: a multilayer piezoelectric element, having internal electrodes laminated having a piezoelectric body layer in-between and a pair of external electrodes formed on the entire side surfaces extending along laminating direction and electrically connected to the internal electrodes, a wiring part connected to the plurality of external electrodes via a solder part, wherein a solder is solidified, a first resin part interposed between one end surface in the laminating direction of the multilayer piezoelectric element and a mounting surface of a connection member placed to face the one end surface to join the one end surface and the mounting surface, wherein: the first resin part is continuous from one of the external electrodes to the other external electrode; and the first resin part integrally covers the solder part formed on each of the external electrodes.
