PROBLEM TO BE SOLVED: To suppress the temperature rise in a part of an ultrasonic examination probe to be applied to the human body in a medical examination. SOLUTION: A heat absorbing surface of a Peltier element 2 is closely stuck to parts of an ultrasonic vibrator 6 and an electronic circuit 5, which are stored in a part close to the part of the ultrasonic probe 1 to be applied to the human body and are major heat generating sources, forcedly absorbs the heat and radiates it as far infrared radiation from a heat radiating surface. A heat radiating surface of a Peltier element 3 is closely stuck to a heat radiating part of a case, its heat absorbing surface receives and absorbs the heat rays radiated from the heat radiating surface of the Peltier element 2 and transmits and radiates it from the heat radiating surface to the case 7.
