Claims

[Scope of utility model registration request]

(1) A plurality of rectangular parallelepiped vibrators with planar electrodes on the front and back surfaces are lined up at intervals and fixed on a load material to form a vibrator group. An acoustic matching layer having electrodes is provided, and the electrodes on the back side are bonded to each other so that they are in contact with the front electrodes of the vibrator group, and a common grounding lead is drawn out from the end of the vibrator group in the column direction. Ultrasonic probe.

(2) As a transducer group, an auxiliary transducer that does not emit ultrasonic waves is provided at the end in the column direction, and as an electrode of the acoustic matching layer, it can reach the surface electrode of the auxiliary transducer and be bonded to the surface of the transducer group. The ultrasonic probe according to claim 1, which is a registered utility model, and further includes a common grounding lead drawn out from the auxiliary transducer.

(3) Make the length of the acoustic matching layer and the electrode provided on its back surface longer than the length of the transducer group in the column direction, and attach it to the surface of the transducer group so that it protrudes from the end of the transducer group in the column direction. The ultrasonic probe according to claim 1, which is a utility model, and further has a common grounding lead drawn out from the protruding portion.
