Ultrasonic probe and ultrasonic diagnostic device

摘要

An ultrasonic probe includes at least one transmission element layer for transmitting ultrasonic waves, at least one reception element layer for receiving ultrasonic waves and which is provided with an electrode on each of both surfaces opposed in a direction of a thickness thereof, and at least one matching layer for matching acoustic impedance. These layers are arranged in this order in a direction of transmitting the ultrasonic waves. The reception element layer is provided with a projecting portion projecting in a direction of elevation from upper and lower layers which sandwich the two electrodes respectively formed on both surfaces of the reception element layer, and at least one of the electrodes is formed by extending to the projecting portion.

1. An ultrasonic probe comprising:
at least one transmission element layer for transmitting ultrasonic waves; at least one reception element layer for receiving ultrasonic waves, wherein an electrode is provided on each of both surfaces opposed in a direction of thickness of the reception element layer; a flexible substrate provided with conductive sections provided in two layers on opposite surfaces thereof that are opposed in a direction of thickness of the flexible substrate; and at least one matching layer for matching acoustic impedance; wherein the transmission element layer, the reception element layer, and the matching layer are arranged in this order in a direction of transmitting the ultrasonic waves; wherein the reception element layer is provided with a projecting portion projecting in a direction of elevation from upper and lower layers which sandwich the electrodes respectively formed on both surfaces of the reception element layer; wherein the electrodes provided on both of the surfaces of the reception element layer extend so as to be provided on both surfaces of the projecting portion which are opposed in a direction of thickness of the projecting portion, and the electrodes provided on both of the surfaces of the projecting portion are respectively connected to the two layers of the conductive sections provided on the opposite surfaces of the flexible substrate; and wherein the reception element layer is formed of an organic resin, and the projecting portion together with the electrodes are bent toward the transmission element layer.
