摘要:
An ultrasonic probe which has high propagation efficiency of ultrasound and can obtain a high resolution ultrasonic diagnostic image, the ultrasonic probe includes an ultrasonic transducer including: a piezoelectric body which generates ultrasound; and a first matching layer which is disposed in a predetermined direction as seen from the piezoelectric body and is for performing acoustic matching between the piezoelectric body and a subject, wherein the first matching layer includes a plurality of matching regions which have a uniform thickness in the predetermined direction, are arranged in a direction perpendicular to the predetermined direction, and include at least two matching regions having frequency characteristics of ultrasound transmittance different from each other.
