Abstract
An ultrasound transducer according to an embodiment has two-dimensionally arranged ultrasound vibrators. A wiring board block is a laminate of wiring boards which are arranged along the row direction in the arrangement. The wiring board has a first surface facing a rear surface of the ultrasound vibrators and a second surface on its opposite side. First connection parts are provided on the first surface corresponding to the arrangement, and are conducted with back electrodes of the vibrators. Second connection parts are provided on the second surface, and are provided corresponding to the first connection parts. Connecting leads establish conductivity between the first and second connection parts through a fourth surface which is perpendicular to the second and third surfaces. Electronic circuits are connected to the second surface of the wiring board block, and are conducted with the second connection parts.
