Ultrasonic array transducer, manufacturing method of ultrasonic array transducer, ultrasonic probe and ultrasonic diagnostic apparatus

摘要

To provide an ultrasonic array transducer having high impedance matching effect and excellent productivity, a method of manufacturing an ultrasonic array transducer, an ultrasonic probe and an ultrasonic diagnostic apparatus.An ultrasonic array transducer according to the present technology includes an ultrasonic transducer (130), a semiconductor chip, and (140). The ultrasonic transducer (130) constitutes an array. The semiconductor chip (140) is joined to each of the ultrasonic transducers (130) to form an impedance matching circuit.
