Abstract
An method of manufacturing a piezoelectric element easily and surely forms polymer coatings on peripheral end faces of the piezoelectric element without deteriorating a yield of the piezoelectric element. The method includes steps of cutting a piezoelectric element out from a base piezoelectric material plate so that peripheral end faces are formed to define a peripheral shape of the piezoelectric element, and forming polymer coatings on at least objective areas of the peripheral end faces of the piezoelectric element by vapor deposition polymerization, respectively.
