PROBLEM TO BE SOLVED: To provide a small-sized ultrasonic probe in which a plurality of ultrasonic oscillators is mounted at high-density.SOLUTION: The ultrasonic probe 1 includes: ultrasonic oscillators 5 aligned in a circumferential direction an acoustic matching layer 41 provided on the ultrasonic oscillators 5 a bent part 47 provided between ultrasonic oscillators 5 adjacent to each other in the circumferential direction and having an electrode layer serving as an electrode of the ultrasonic oscillators 5 adjacent to each other. The ultrasonic probe 1 may be configured so that the electrode layer is exposed to the outside from the bent part 47.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】複数の超音波振動子を高密度に実装した小型の超音波プローブを実現すること。【解決手段】周方向に配列された超音波振動子5と、前記超音波振動子5上に設けられた音響整合層41と、前記周方向に隣接する前記超音波振動子5間に設けられ、当該隣接する超音波振動子5の電極となる電極層を有する屈曲部47と、を備えた超音波プローブ1である。さらに、前記屈曲部47において前記電極層が露出してなる超音波プローブ1を構成してもよい。【選択図】図1
