Abstract: A ultrasonic vibration cutting tool which can optimize materials as in a separate type and can improve the transmission efficiency of ultrasonic vibration as in an integrated type. The ultrasonic vibration cutting tool comprises a ring-shaped projection and a blade essentially composed of diamond and held by the ring-shaped projection both of which are formed on the peripheral surface of a vibration conversion portion provided on a resonator, and the outer diameter of the blade is set larger than the outer diameter of the ring-shaped projection.
