ABSTRACT OF THE DISCLOSURE An electro-mechanical transducer having a first layer made of piezoelectric material having opposing major surfaces, a pair of electrodes formed on the major surfaces of the first layer, respectively, and a second layer clamped at its one surface to one of the surfaces of the first layer. In this case, the first layer has a Young's modulus of E, the second layer has a Young's modulus Ex in one direction and a Young's modulus Ey in the direction perpendicular to the one direction in the major surface, the Young's moduli E, Ex, Ey satisfy the relation E > Ey, Ex > Ey, and one end of the first and second layers along the one direction is clamped.
