層深さ測定用超音波探触器。 An incident ultrasonic wave is transmitted to a surface modified layer formed on the surface of the main body that has a different structure from the main body, and the incident ultrasonic wave is reflected at the interface between the surface modified layer and the main body, and the reflected ultrasonic wave is Accordingly, it is used in a measurement method in which the depth of the surface modified layer is determined by receiving the outgoing ultrasonic wave emitted from the surface modified layer and measuring the time from the emission of the incident ultrasonic wave to the reception of the outgoing ultrasonic wave. an ultrasonic probe comprising: a transmitting transducer that makes the incident ultrasonic waves obliquely enter the surface modified layer; a receiving vibration that receives the emitted ultrasonic waves obliquely emitted from the surface modified layer; an attenuation suppressor that is in close contact with the transmitting surface of the transmitting vibrator, the receiving surface of the receiving vibrator, and the surface of the surface modified layer to suppress attenuation of the incident and output ultrasonic waves while allowing transmission thereof; disposed between the two transducers in order to prevent transmitted ultrasonic waves that do not contribute to measurement due to reflection of the incident ultrasonic waves on the surface of the surface modified layer from transmitting to the receiving transducer side; An ultrasonic probe for measuring the depth of a surface-modified layer consisting of a shield and;
