PROBLEM TO BE SOLVED: To provide a compact transmission/reception element excellent in durability.SOLUTION: A transmission/reception element 1 of a supersonic wave comprises a tabular piezo-electric element 10 and a resin part 20 fixed to the tabular piezo-electric element 10. The resin part 20 includes an annular planar part 21 and a dome part 22 formed inside the annular planar part 21. The annular planar part 21 is fixed to the piezo-electric element 10.SELECTED DRAWING: Figure 1 【課題】小型で耐久性の良い送受信素子の提供。【解決手段】板状の圧電素子10と、前記板状の圧電素子10に固定された樹脂部20を有する超音波の送受信素子1であって、前記樹脂部20が、環状平面部21と前記環状平面部21の内側に形成されたドーム部22を有するものであり、前記環状平面部21が前記圧電素子10に固定されているものである。【選択図】図１
