ABSTRACT:
An ultrasonic transducer comprises: an acoustic matching layer including at least a layer made up of a hard material; a piezoelectric member of which the length dimension is shorter than this acoustic matching layer, which is fixed and disposed at a predetermined position of a layer made up of the hard material which makes up the acoustic matching layer, and divided into a plurality of piezoelectric devices in this disposed state; and a transducer shape-formative member made up of a hard material, wherein, in a state in which the surfaces of the piezoelectric devices divided and formed are disposed on the inner circumferential surface side, the plurality of piezoelectric devices are arrayed in a predetermined shape, fixed and disposed on the surface where the piezoelectric devices of the acoustic matching layer protruding from the piezoelectric devices have been disposed.
