The present invention relates to an overlapping bipolar electrode for high-frequency heat treatment including: a cylindrical electrode body an active electrode body configured to be connected to one terminal of a high frequency generator while being wound from a tip portion of an outer peripheral surface of the body toward a rear end thereof in plural times and a passive electrode body configured to be connected to the other terminal of the high frequency generator while being wound from a tip portion of an outer peripheral surface of the body toward a rear end thereof through the active electrode body in plural times, whereby the heat generation range by high frequency energy radiation generated between the adjacent corresponding active electrode body and passive electrode body matches a lesion of a tubular tissue such as, in particular, a blood vessel, in terms of a form, thereby minimizing a damage of adjacent normal tissues at the time of cauterization and remarkably improving heat treatment efficiency by the electrode.
