PURPOSE:To attain light weight and ease of operation by adhering an ultrasonic wave absorbing body including an air bubble to the rear face of an oscillator in an ultrasonic wave oscillator used for an ultrasonic wave diagnostic device. CONSTITUTION:The ultrasonic wave absorbing body 7 including lots of air bubbles to an urethane resin is adhered to a rear face opposite to the matching layer 6 of the oscillator 2 in the ultrasonic wave probe 1. Since an ultrasonic wave made incident to the ultrasonic wave absorbing body 7 from the oscillator 2 is scattered and absorbed sufficiently by lots of air bubbles 8 while the wave passes through the inside, the thickness of the ultrasonic wave absorbing body is made thin. |
