Abstract:
An ultrasonic vibration apparatus includes a vibrator, wherein the vibrator includes at least two vibration elements to generate ultrasonic vibration when a driving voltage is applied to the vibration elements, at least three electrode portions wherein the vibration elements and the electrode portions is alternately arranged side by side in a vibrating direction, at least the three electrode portions includes at least two first electrode portions and at least one second electrode portion alternately arranged in the vibrating direction, the vibrator integrally vibrates ultrasonically in the vibrating direction when the driving voltage is applied to the first electrode portions and the second electrode portion, and a bridging portion coupling and electrically connecting two first electrode portions of at least the two first electrode portions with each other, and the ultrasonic vibration apparatus further includes an anti-vibration portion to suppress vibration of the bridging portion in any other direction except the vibrating direction.
