Abstract
The piezoelectric element includes first and second sheetsandthat are stacked and burned. In this stacked state, a second electrodeis located on a first long sidehaving a first non-electrode region. Thus, before a conductive filmA is formed, the end face of a first electrodeand the end face of the second electrodeare exposed on lateral surfacesandon the same side and can be observed thereon. Slitsare formed at certain intervals in a lengthwise direction X. The conductive filmA is formed so as to apply a voltage between the second electrodeexposed on a front surfaceand endsand, thereby driving the piezoelectric element only with connection from the front surface
