Abstract
A piezoelectric device that includes a sintered body in which a first conductor portion and a second conductor portion are disposed on both principal surfaces of a piezoelectric ceramic base body. The first conductor portion includes conductive films having a predetermined pattern. An insulating film is formed on the principal surface of the piezoelectric ceramic base body on which the conductive films are disposed such that portions of the conductive films are exposed therethrough. The insulating film has a malleability equal to or greater than that of the conductive films.
