Ultrasound transducer, ultrasound probe, and a method for manufacturing ultrasound transducers

An ultrasound probe, comprising:

• a group of ultrasound vibrators composed of two-dimensionally arranged ultrasound vibrators, each of which includes a piezoelectric transducer in which a front electrode is formed on a front surface that is an ultrasonic radiation surface and in which a back electrode is formed on a rear surface;
• a wiring board block composed of a laminate, along the row direction or the column direction with respect to the two-dimensional arrangement, and including a plurality of wiring boards, wherein each wiring board has a first surface facing said rear surface of said ultrasound vibrators and a second surface on an opposite side to the first surface;
• first connection parts provided on said first surface corresponding to the arrangement of said ultrasound vibrators and to be conducted with said back electrodes;
• second connection parts provided on a third surface that is perpendicular to said second surface;
• connecting leads configured to establish conductivity between said first connection parts and said second connection parts on a fourth surface that is perpendicular to both the second surface and the third surface of said wiring boards;
• and
• electronic circuits configured to be connected to a surface of said wiring board block on which said second connection parts are provided, to be conducted with said second connection parts, and to process signals from said piezoelectric transducers;
• and
• an interface part configured to establish conductivity between an external device and said electronic circuits,
• wherein a shape of an entire arrangement of said ultrasound vibrators is a curved shape;
• and
• the first surface of said wiring board block which faces said rear surfaces of said ultrasound vibrators is formed as a curved shape corresponding to a shape of said rear surfaces, based on the arrangement of said ultrasound vibrators.
