摘要： A base has a plurality of projections or recesses. Each of the projections or recesses corresponds to one channel of vibration elements. Each of the vibration elements has a plurality of MUT elements. Each of the MUT elements transmits and receives ultrasonic waves. A plurality of MUT elements are arranged in each of the projections or recesses. Consequently, each of the vibration elements can transmit and receive ultrasonic waves having radiation surfaces curved along the surfaces of the projections or recesses.
