ULTRASOUND PROBE

Abstract: a transducer array has two dummy transducers adjacent to an effective part. each dummy transducer has a conductive part consisting of a dummy piezoelectric layer and a dummy reflective layer. a ground line in a wiring sheet is electrically connected to a ground film through two conductive parts. two second slits are provided between the two dummy transducers and the effective part. the wiring sheet has a lower wiring pattern, an upper wiring pattern, and a via group.
