Ultrasound probe

Abstract

An sound probe according to the present disclosure includes: an array of transducer elements in which a plurality of transducer elements are arranged in a first direction and which makes an interconversion between an electric pulse and an ultrasonic wave; an acoustic lens which has a convex surface in a transmission direction of the ultrasonic wave on a cross section that is parallel to the first direction and the transmission direction and which converges the ultrasonic waves transmitted from the plurality of transducer elements; and at least two acoustic adjustment layers which are made of a material that has a different sound velocity from the acoustic lens, which are arranged between at least two of the transducer elements that are arranged in the first direction and the acoustic lens, and of which at least one of the material and a thickness of each of the at least two acoustic adjustment layers in the transmission direction are different from each other.
