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 tubeis loosely mounted onto the outer periphery of a small diameter metal core wire(diameter, 0.7 mm or so) connected to an electromagnetic wave irradiating electrodesuch that it covers the short tube at the root of the electrode. The short tubeis fixed by a heat resisting coating layermade of tetrafluoroethylene or the like. A rod-shaped rigid metal core wirehaving a relatively larger diameter is connected in a unified form to the small diameter metal core wireand a heat resisting coating layeris also applied onto the core wire
