摘要：
It becomes possible to obtain high sound pressure in a high frequency domain by a capacitive ultrasonic transducer which comprises a membrane on which one electrode is formed, a cavity constructed in its backface, and a substrate on which these are mounted and supported and on whose surface an electrode is provided, on a surface in an ultrasonic transmission and reception side, characterized in that the membrane comprises two or more layers, and at least one layer of them comprises a high dielectric constant film.
摘要（中）：
可以通过电容式超声换能器在高频域获得高声压，该电容式超声波换能器包括其上形成有一个电极的膜，在其背面构成的空腔以及在其上安装和支撑这些电极的基板 在超声波发送和接收侧的表面上设置电极，其特征在于，所述膜包括两层或更多层，并且其至少一层包括高介电常数膜。
