BACKING MEMBER, ULTRASONIC PROBE, AND ULTRASONIC IMAGE DISPLAY APPARATUS

摘要

An ultrasonic probe that can release heat generated from an ultrasonic vibrator, to a side opposite to a surface of the ultrasonic probe: a backing member 27 provided in an ultrasonic probe 1 is mounted to a side opposite to a transmission direction of ultrasonic wave to a subject with respect to an ultrasonic vibrator 7 that transmits the ultrasonic wave to the subject, the backing member 27 including a plate-like backing material 24, and a thermal conductor 25 and thermal conductive plate 26 that are made of a material having thermal conductivity higher than that of the backing material 24, wherein the thermal conductor 25 is buried in the backing material 24 and formed to have a columnar shape so as to reach both surfaces of the plate-like backing material 24, and the thermal conductive plate 26 is provided on at least the surface nearest the ultrasonic vibrator 7, out of the surfaces 24a and 24b of the plate-like backing material 24.
