Abstract (en)
A dummy piezoelectric element (7) is disposed at least at one of the ends of an array of piezoelectric vibration elements. A region not including internal electrodes is provided in the vicinity of the outer side surface of the dummy piezoelectric vibration element 7 to be formed. When the outer side surface of the dummy piezoelectric element 7 is cut, a shift of a cutting line from a correct cutting line, which is due to high hardness of the internal electrodes, is minimized. <IMAGE>
