Abstract
An ultrasonic transducer includes a diaphragm, one or more frame bodies extending in a longitudinal direction and bonded to the diaphragm, and one or more ultrasonic vibrators attached to the respective one or more frame bodies and facing the diaphragm with a space in between. The diaphragm is structured to resonate and vibrate in a direction orthogonal to the diaphragm in a phase opposite to a phase of the one or more ultrasonic vibrators. A dimension in the longitudinal direction inside the one or more frame bodies is larger than a dimension in a lateral direction orthogonal to the longitudinal direction inside the one or more frame bodies. One or more cavities cause an external space on an opposite side from the one or more frame bodies with respect to the diaphragm and an internal space inside the one or more frame bodies to communicate with each other.
