ABSTRACT:
An electrode rod for treating a biological tissue is provided to properly carry out a surgical operation wherein a sufficient thermal shield is applied onto a core wire connected to an electrode at the root of the electrode. A heat resisting ceramic or polyimide non-metallic short tube15is loosely mounted onto the outer periphery of a small diameter metal core wire14(diameter, 0.7 mm or so) connected to an electromagnetic wave irradiating electrode13such that it covers the short tube at the root of the electrode13. The short tube15is fixed by a heat resisting coating layer16made of tetrafluoroethylene or the like. A rod-shaped rigid metal core wire14ahaving a relatively larger diameter is connected in a unified form to the small diameter metal core wire14and a heat resisting coating layer16ais also applied onto the core wire14a.
