Abstract:
1. An ultrasound transducer, 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 a 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, wherein a shape of an entire arrangement of said ultrasound vibrators is a curved shape; and the first surfaces of said wiring boards which face said rear surfaces of said ultrasound vibrators are formed as a curved shape corresponding to a shape of said rear surfaces, based on the arrangement of said ultrasound vibrators.
