1. A method of fabricating a lamination-type displacement device, comprising the steps of:

  • forming thin films of an electromechanical transducer material alternately with internal electrodes of a conductive material to form a laminate in which the internal electrodes are exposed at different parallel side surfaces;

    forming a protective film on and around alternate layers of the internal electrodes at one side surface;

    forming a protective film on and around the internal electrodes other than said internal electrodes at the other side surface;

    selectively polishing the side surfaces of the laminate except for the protective films; and

    removing the protective films.
