Abstract

PURPOSE:To increase a touch area with an external electrode and to obtain an electrical and mechanical connecting with the external electrode without fail by providing a notch at the side surface exposure part of an internal electrode. CONSTITUTION:A piezoelectric element 1 and an internal electrode layer 3 are laminated alternately, and external electrodes 2 and 2' are formed on 2 surfaces perpendicular in a laminating direction. An internal electrode layer 3 is exposed to 2 side-surfaces on every other layer, and a notch 4 is formed at this exposure part. The external electrode 2 is brought into contact with the part including this notch 4.
