PROBLEM TO BE SOLVED: To provide an ultrasonic probe capable of improving detection performance (S/N) of an ultrasonic wave from a subject.SOLUTION: In order to reduce multiple reflection of an ultrasonic wave generated between a subject and a part of a housing where a sensor is not installed, an ultrasonic probe 180 includes a plurality of ultrasonic sensors 200, and a housing which has a concave part recessed toward a subject 120 to be arranged at a measurement position when measurement is performed, and supports the plurality of ultrasonic sensors. The ultrasonic sensors are arranged so that the sensor surfaces are directed toward a subject side. The housing includes an ultrasonic reflection control layer on the subject side surface.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】被検体からの超音波の検出性能(S/N)を向上させる事ができる超音波プローブを提供する。【解決手段】被検体とセンサが配置されていない筐体の部分との間で生じる超音波の多重反射を低減するために、超音波プローブ180は、複数の超音波センサ200と、測定の際に測定位置に配置されるべき被検体120に向かって凹状となる凹部を有し、複数の超音波センサを支持する筐体と、を備える。超音波センサは、センサ面が被検体側に向くように配置され、筐体は、被検体側の面に超音波反射制御層を有する。【選択図】図1
