PROBLEM TO BE SOLVED: To provide an ultrasonic probe capable of further improving sensitivity.SOLUTION: The ultrasonic probe includes: a plurality of piezoelectric elements 201 a substrate 202 an intermediate layer 203 and a backing material 204. The plurality of piezoelectric elements 201 is arranged at a predetermined pitch. The substrate 202 is disposed on a back surface of the plurality of piezoelectric elements 201 and includes a signal line for signal transmission with the plurality of piezoelectric elements 201 and a wiring pattern for drawing a signal to the outside. The intermediate layer 203 is disposed on the back surface of the substrate 202, and a plurality of layer materials is arranged at a predetermined pitch in the arrangement direction of the plurality of piezoelectric elements 201. The backing material 204 is disposed on the back surface of the intermediate layer 203.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】より感度を向上させることができる超音波プローブを提供する。【解決手段】超音波プローブは、複数の圧電素子201、基板202、中間層203およびバッキング材204を含む。複数の圧電素子201は、所定のピッチで配列される。基板202は、複数の圧電素子201の背面に配置され、複数の圧電素子201との信号伝送のための信号線路と信号を外部に引き出す配線パターンとを含む。中間層203は、基板202の背面に配置され、所定のピッチで複数の圧電素子201の配列方向に複数個の層材が配列される。バッキング材204は、中間層203の背面に配置される。【選択図】図2
