A method of manufacturing an ultrasonic probe including the steps of forming a plurality of first slits on a layered assembly having a first imner electrode member and a second inner electrode member through a top surface of the layered assembly and forming a plurality of second slits through a bottom surface of the layered assembly, forming a first vertical electrode layer on each side surface within each of the first slits, forming a second vertical electrode layer on each side surface within each one of the second slits and forming a plurality of separating slits on the layered assembly to divide the layered assembly into a plurality of transducer elements.
