Claims

[Scope of utility model registration request]

A transmitting transducer, one receiving transducer, a transmitting delay material and a receiving delay material to which the transmitting transducer and the receiving transducer are respectively attached, and the transmitting delay material and the receiving delay material. In an ultrasonic probe equipped with an acoustic shielding plate provided in between and a probe case housing the above-mentioned components, the transmitting delay material and the receiving delay material or the transmitting delay material to be inspected. An ultrasonic probe characterized in that the surface facing the material to be inspected is formed such that the gap between the surface facing the material and the material to be inspected increases from the acoustic shielding plate side to the outside of the probe case. ，
