Claims

[Claims for Utility Model Registration] (1) An ultrasonic vibrator that transmits and receives ultrasonic waves using a plate-shaped piezoelectric element attached with a conical resonator to increase sensitivity, A piezoelectric element is placed on a support base that supports both ends, and the resonator is arranged in an inverted state with the apex of the resonator in contact with the center of the piezoelectric element, and the periphery of the bottom of the resonator,
An ultrasonic transducer characterized in that a case that houses and holds both ends of a piezoelectric element and a support base is made of an elastic cushioning material. (2) The ultrasonic wave according to claim 1 of the utility model registration claim, characterized in that the top surface of the case where the bottom surface of the resonator is exposed is formed flush with or lower than the bottom surface of the resonator. vibrator.
