摘要：
In order to provide an ultrasonic probe capable of suppressing the influence of multiple reflections occurring on the interface of a transducer with a CMUT chip and a backing layer, an ultrasonic probe of the present invention has a structure where an acoustic lens 14, transducers 11-1 to 11-m, and a backing layer 12 are laminated. Each of the transducers 11-1 to 11-m has a CMUT chip, and the backing layer 12 is formed of a material with a value of substantially the same acoustic impedance as the acoustic lens 14.
