Abstract:
1. An ultrasound diagnostic equipment comprising: an ultrasound probe for transmitting and receiving ultrasound waves with respect to a test subject, and an ultrasound diagnostic equipment body for controlling the ultrasound probe by applying driving signals to the ultrasound probe, wherein the ultrasound probe comprises: an electroacoustic conversion unit formed by arranging a plurality of piezoelectric devices and a plurality of acoustic matching layers in a predetermined direction, each of the plurality of piezoelectric devices being an electroacoustic conversion device, the plurality of acoustic matching layers being respectively stacked on the plurality of piezoelectric devices; and a signal flexible board transferring electric signals to and from the plurality of piezoelectric devices for transmission and reception of ultrasound waves, wherein the signal flexible board is stacked on the plurality of acoustic matching layers wherein an incision passing through the plurality of piezoelectric devices in respective thickness directions of the piezoelectric devices and extending into the corresponding acoustic matching layers stacked on the respective piezoelectric devices is provided in parallel to the arrangement direction, and wherein the acoustic matching layers are longer in length in the direction perpendicular to the arrangement direction than the piezoelectric devices.
