Abstract
An sound probe includes an array of transducer elements with a plurality of transducer elements arranged in a first direction and which makes an interconversion between an electric pulse and an ultrasonic wave; an acoustic lens with 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 made of a material that has a different sound velocity from the acoustic lens and arranged between at least two of the transducer elements. 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.
