Abstract
A resin is provided so as to cover four side faces of a piezoelectric multilayer body integrally and thus is effectively prevented from peeling from the piezoelectric multilayer body, whereby high adhesion is attained between the piezoelectric multilayer body and the resin. At the same time, the resin covers dicing surfaces in the side faces of the piezoelectric multilayer body, thereby effectively restraining the piezoelectric body and the electrodes from producing particles.
