ULTRASONIC APPARATUS

Abstract:

[Object] To provide an ultrasonic apparatus having a high transmission strength, high reception sensitivity, reliability, and excellent mass productivity. [Solving Means] An ultrasonic apparatus according to the present technology includes an ultrasonic wave transmitting element and an ultrasonic wave receiving element. The ultrasonic wave transmitting element is arranged on a first surface side of the ultrasonic apparatus and has a structure in which a piezoelectric material layer is sandwiched by an upper electrode and a lower electrode. The ultrasonic wave receiving element is arranged between a second surface opposite to the first surface side of the ultrasonic apparatus and the ultrasonic wave transmitting element and has a MEMS structure.
