PROBLEM TO BE SOLVED: To provide an ultrasonic probe capable of preventing reduction in an acoustic property of an acoustic lens.SOLUTION: An ultrasonic probe comprises: a vibrator array 20 an acoustic lens 28 which is arranged on an ultrasonic wave transmission/reception surface side of the vibrator array 20 one or more matching layers which are interposed between the acoustic lens 28 and the vibrator array 20 and a cylindrical frame body 30 which surrounds the periphery of the vibrator array 20, both ends of which are opened, and which is installed in the acoustic lens 28. The third matching layer located the closest to the acoustic lens 28 among the one or more matching layers is stuck to the end surface of the frame body 30 without slack in order to cover the opening of the frame body 30.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】音響レンズの音響特性の低下を防ぐことができる超音波探触子を提供する。【解決手段】超音波探触子は、振動子アレイ20と、振動子アレイ20の超音波の送受波面側に配置される音響レンズ28と、音響レンズ28と振動子アレイ20との間に介在する1以上の整合層と、振動子アレイ20の周囲を囲み、その両端が開口された筒状の枠体30であって、音響レンズ28に設置される枠体30と、を備え、1以上の整合層のうち最も音響レンズ28側に位置する第三整合層は、枠体30の開口を覆うべく枠体30の端面にたるみなく貼着される。【選択図】図2
