PROBLEM TO BE SOLVED: To provide an ultrasonic device and an ultrasonic measurement device capable of accurately measuring a shape of a measurement object region with irregularities.SOLUTION: There is provided an ultrasonic device in which a plurality of ultrasonic element arrays having a plurality of ultrasonic transmission/reception parts are connected at variable angles between them. The plurality of ultrasonic transmission/reception parts are disposed in a first direction intersecting with a thickness direction of the ultrasonic element arrays, and the plurality of ultrasonic element arrays are connected at angles variable in the first direction. In a plane view in a second direction intersecting with the thickness direction and the first direction, normal lines passing through the center of the transmission/reception surfaces of the plurality of ultrasonic element arrays cross at one point.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】凹凸を有する測定対象部位の形状を高精度に測定可能な超音波デバイス、及び超音波測定装置を提供する。【解決手段】複数の超音波送受部を有する複数の超音波素子アレイが互いの角度を可変として連結された超音波デバイスであって、複数の前記超音波送受部は、前記超音波素子アレイの厚み方向と交差する第一方向に配置され、複数の前記超音波素子アレイは、前記第一方向に角度を可変として連結され、前記厚み方向と前記第一方向とに交差する第二方向から平面視して、複数の前記超音波素子アレイの超音波の送受信面の中心を通る法線は一点で交わる、ことを特徴とする。【選択図】図4
