Abstract:
An array-type ultrasonic vibrator according to the present invention has an acoustic matching layer that has a plate-like body made of a material having a lower acoustic impedance than a plurality of piezoelectric elements. Signal wiring is formed on the plate-like body of the acoustic matching layer. Accordingly, for this array-type ultrasonic vibrator, the signal wiring can be easily formed without using additional components.
