Ultrasonic probe

A highly sensitive ultrasonic probe is provided by effectively damping the ultrasonic wave emitted from a piezoelectric oscillator (1) toward the back surface by means of a backing layer (4) and reducing the reflected wave returning to the piezoelectric oscillator (1) side. The thickness of the backing layer (4) is reduced to a value much smaller than conventional. The ultrasonic probe is provided with a piezoelectric oscillator (1) for generating an ultrasonic wave and a backing layer (4) joined to the back surface of the piezoelectric oscillator (1) and adapted for damping the ultrasonic wave which is emitted toward the back surface of the piezoelectric oscillator (1) and has an opposite phase to the phase of the ultrasonic wave emitted toward the front surface of the piezoelectric oscillator (1). In the backing layer (4), a plurality of sound tubes (5) having different lengths on the basis of the principle of sound wave superposition are arranged in such a way that the longitudinal direction of the sound tubes (5) agrees with the directions in which the ultrasonic waves generated from the piezoelectric oscillator (1) travel toward the front and back surfaces. The sound tubes (5) damp the whole or part of the ultrasonic wave emitted by the piezoelectric oscillator (1) to the backing layer (4) side.
