Piezoverbound, ultrasonic probe for an ultrasonic diagnostic device, ultrasonic diagnostic device and process for making a piezo band

摘要

A composite sheet unit (6) in which a plurality of sintered piezoelectric thin wires (33) are arranged in a uniform direction on a surface of a resin layer (22) is prepared, and a plurality of the same are laminated and integrated so that the sintered piezoelectric thin wires (33) are positioned between the resin layers (22). Here, a curing resin may be impregnated therein so as to form resin-impregnated-cured portions (23). Then, the lamination is cut in a direction crossing a lengthwise direction of the sintered piezoelectric thin wires (33), so that a piezocomposite is obtained. Cut surfaces may be ground. By so doing, it is possible to provide a highly reliable piezocomposite having a fine structure at low cost, and to provide an ultrasonic probe for an ultrasonic diagnostic equipment, as well as an ultrasonic diagnostic equipment.
