Abstract:
1. An ultrasound transducer, comprising: a plurality of two-dimensionally arranged piezoelectrics, electrodes arranged on the respective plurality of piezoelectrics, a non-conductive acoustic matching layer with a first surface on the electrode side and a second surface on the opposite side of the first surface, two-dimensionally arranged according to the piezoelectrics, a conductive acoustic matching layer arranged on the second surface side, and a substrate arranged on the opposite side of the non-conductive acoustic matching layer with respect to the conductive acoustic matching layer, wherein, a plurality of grooves are formed which penetrates the non-conductive acoustic matching layer between the first surface and the second surface, and extends into mid-way of the piezoelectrics of the first surface side or mid-way of the conductive acoustic matching layer of the second surface side, and the electrode and the substrate are electrically conducted via the grooves.
