Ultrasonic probe with conductive acoustic matching layer

摘要

An ultrasonic probe includes a piezoelectric oscillator layer (3) having plural arranged piezoelectric oscillators for transmitting and receiving ultrasonic waves and plural electrodes formed in the piezoelectric oscillators, an acoustic lens (5) for focusing or diffusing the ultrasonic waves, and an acoustic matching layer (4a) that is provided between the piezoelectric oscillator layer and the acoustic lens and includes a resin base and fine particles, which have electric conductivity, mixed in the resin base. <IMAGE>
