Abstract
A multilayered piezoelectric element in which braking to displacement of piezoelectric material layers is suppressed and insulating films suitable for thinning of the piezoelectric material layers are formed. A method of manufacturing the element includes the steps of: (a) forming a multilayered structure including piezoelectric material layers, at least one first electrode layer, and at least one second electrode layer; (b) discharging a liquid synthetic resin from a nozzle provided in a dispenser to apply it to an end portion of the first electrode layer in a first region within side surfaces of the multilayered structure and curing the liquid synthetic resin to form a first insulating film; and (c) discharging the liquid synthetic resin from the nozzle to apply it to an end portion of the second electrode layer in a second region and curing the liquid synthetic resin to form a second insulating film.
