A handpiece-type high-frequency vibration cutting device includes a housing (10)； a vibration device (21)； a holding member (11)； a tool (12)； and a controller (20) to control the operations of the vibration device (21). The controller (20) controls the vibration of the tool (12) due to the vibration device (21) such that the vibration is burst oscillation in which vibration and stop of vibration are repeated. The controller (20) also controls the entire burst frequency f1 of the tool (12) to be included in the range of 1 to 8 [Hz], one cycle of the burst frequency f1 including a burst period with the holding member (11) vibrating and a stop period with the tool (12) not vibrating. The controller (20) also controls the vibration frequency f2 of the tool (12) during the burst period such that the vibration frequency f2 is in the range of 20 to 60 [kHz].
