ULTRASONIC PROBE AND ULTRASONIC ENDOSCOPE WITH ULTRASONIC PROBE

摘要

Disclosed herein is to allow a reduction in diameter of an ultrasound probe and an ultrasound endoscope and allow reliable and easy electrical connection of signal lines extending from ultrasound transducers. A transducer wiring pad group 102 provided in a distal end portion of an ultrasound transducer printed circuit board 101 provided with signal patterns that transmit and receive signals to and from a plurality of ultrasound transducers, a flexible printed circuit board wiring pad group 108 arranged in a longitudinal axis direction of the ultrasound transducer printed circuit board 101, a second signal pattern group 106 that is connected between the transducer wiring pad group 102 and the flexible printed circuit board wiring pad group 108 and bends at substantially 90 degrees in the middle thereof, and a relay flexible printed circuit board 121 that is connected to the flexible printed circuit board wiring pad group 108 and changes a direction of a signal pattern into the longitudinal axis direction are provided.
