Claims

[Scope of utility model registration request]

Along the bottom wall of the main body of the ultrasound probe, on the inside of the main body,
In an ultrasonic probe in which a large number of ultrasonic transducing elements including piezoelectric elements are arranged, and a groove for an extraction needle is formed on the front or back side of the main body from the top wall to the bottom wall of the main body, An ultrasonic probe characterized in that the thickness of the piezoelectric element near the piezoelectric element is greater than the thickness of the piezoelectric element at other positions.
