Abstract
A fixed frame () is fixed to an external member. An ultrasonic oscillator () is disposed inside the fixed frame () and includes a flexible first substrate and a first piezoelectric element deposited on the first substrate in the form of a thin film. The ultrasonic oscillator () is warped in response to expansion or contraction of the first piezoelectric element and generates ultrasonic waves. Actuator units () include a flexible second substrate coupling the first substrate to the fixed frame () and a second piezoelectric element deposited on the second substrate in the form of a thin film. The actuator units () are warped in response to expansion or contraction of the second piezoelectric element and cause the ultrasonic oscillator () to swing relative to the fixed frame (). The fixed frame (), the first substrate, and the second substrate are composed of the same substrate.
