Disclosed is a bipolar high-frequency electric knife, comprising a cutter portion (21), a main body part (22) and an operation portion (23). The cutter portion (21) comprises a first electrode portion (3), a second electrode portion (1) and an insulation member (11). The main body part (22) comprises a position-limiting part (5) and an insulation sheath (6). The operation portion (23) comprises a handle (7), a button (8), a socket (9), a first wire (10a) and a second wire (10b). The bipolar high-frequency electric knife can not only prevent the perforation of the basal layer of tissue caused by high-frequency electric shock during cutting, but can also ensure that the two electrodes are simultaneously in full contact with the tissue in any direction or at any angle, thereby guaranteeing the reliability of surgical cutting.
