To provide a high-frequency electrode and a high-frequency incision instrument that can make a depth-wise incision of a predetermined depth in tissue in a short time by a simple operation.SOLUTION: A high-frequency electrode (1) includes an incision part formed of an insulating part and an electrode (21, 22) of which a conductor (2) is exposed from the insulating part and configured to able to incise, by a current flowing through the conductor, tissue in an incision direction (C) perpendicular to the longitudinal direction of the electrode. The electrode comprises a first electrode (21) and a second electrode (22) spaced apart and exposed from the first electrode. At least a portion of the first electrode is exposed from the insulating part at a position different from the second electrode in the incision direction.SELECTED DRAWING: Figure 3【課題】簡単な操作により短時間で組織を深さ方向に所定量切開できる高周波電極及び高周波切開具を提供することを目的とする。【解決手段】本高周波電極（１）は、絶縁部と、前記絶縁部から導体（２）が露出した電極（２１，２２）とで形成され、前記導体が通電されることにより前記電極の長手方向に直交する切開方向（Ｃ）に組織を切開可能に構成された切開部を備え、前記電極は、第一電極（２１）と、前記第一電極と離間して露出する第二電極（２２）とを備え、前記第一電極の少なくとも一部が、前記第二電極とは前記切開方向に異なる位置で前記絶縁部から露出している。【選択図】図３
