A backing material for suppressing the surface temperature rise of an ultrasonic probe. This backing material is provided on a back face of at least one vibrator for transmitting and/or receiving ultrasonic waves in an ultrasonic probe, and includes: a backing base material containing a polymeric material; and a heat conducting fiber provided in the backing base material, having a larger coefficient of thermal conductivity than that of the backing base material, and running through without disconnection from a first face of the backing material in contact with the at least one vibrator to a second face different from the first face.
