ABSTRACT:
An ultrasonic transducer includes a piezoelectric member that includes electrodes on two plane portions. The electrodes are fixed and disposed such that part of an acoustic matching layer protrudes at a predetermined position of the hard layer, which makes up the acoustic matching layer. The piezoelectric member further includes a substrate formed with an electroconductive pattern and is fixed and disposed on the face of the hard layer. The piezoelectric member and the substrate are divided to array piezoelectric devices. The electroconductive pattern of the substrate, and at least part of the electrodes of the piezoelectric member that is electrically connected to at least part of this electro conductive pattern are directed in the same direction. The substrate is disposed adjacent to the piezoelectric member, the electroconductive pattern on the substrate, and the electrodes of the piezoelectric member. The electrodes are divided, and are electrically connected via an electroconductive member.
