[PROBLEMS] To provide an ultrasonic probe capable of easily and accurately measuring subcutaneous fat without using a jelly-like acoustic impedance matching medium. I do. SOLUTION: When a suction pad 6 is brought into direct contact with the skin of a subject, and a suction pump 9 is operated to suck air in an air chamber 7 through a suction hose 8, the suction pad 6 is surrounded by the skin of the subject. The air in the closed space is sucked through the air holes 10, and the surfaces of the suction pad 6 and the protective film 5 are in close contact with the skin. In this state, a pulse voltage is applied between the lead wires 11 and 12, an ultrasonic wave is generated from the piezoelectric body 4, and a reflected wave from the body is received by the piezoelectric body 4, whereby the thickness of fat is measured. |
