An electrode assembly of an electrosurgical knife in which a metallic conduit is used as a conductive passage is provided on an outer sleeve of the electrosurgical knife. The electrode assembly includes a metallic conduit. The rear end of the metallic conduit is connected with a conduit within the outer sleeve. The outer periphery of a front end of the metallic conduit is provided with an insulating sleeve. The insulating sleeve is assembled with the mouth of the outer sleeve. Further, the mouth of the metallic conduit is provided with an electrode block and is connected with the insulating sleeve. Finally, the outer sleeve is provided with an electrode lead therein. The lead is electrically connected with the metallic conduit. With the electrode conduit, an external power supply can be conducted to the electrode block via the metallic conduit, so that the electrode assembly of the electrosurgical knife can perform a normal action. In this way, the convenience in assembling the electrosurgical knife can be improved.
