TRANSMISSION/RECEPTION ELEMENT OF SUPERSONIC WAVE

摘要

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
