Ultrasonic transducer

This ultrasonic transducer is provided with a housing, a piezoelectric element, a wiring member, a foam member, and a vibration damping material. The housing has a bottom wall. The piezoelectric element is disposed on the bottom wall in the housing. The wiring member is electrically connected to the piezoelectric element. The foaming member is disposed on the piezoelectric element. The damping material is disposed between the piezoelectric element and the foaming member. The foam member has a bottom surface facing the piezoelectric element in the thickness direction of the piezoelectric element. A plurality of recesses are formed on the bottom surface. The vibration damping material joins the piezoelectric element and the bottom surface. 本发明的超声波换能器具备：壳体、压电元件、配线构件、发泡构件以及减振材料。壳体具有底壁。压电元件在壳体内配置于底壁上。配线构件与压电元件电连接。发泡构件配置于压电元件上。减振材料配置于压电元件和发泡构件之间。发泡构件具有在压电元件的厚度方向上与压电元件相对的底面。在底面具有形成有多个凹陷。减振材料将压电元件和底面接合。
