Abstract
An electrode device of an electrosurgical instrument is known, comprising at least one electrically conductive electrode section and an electrically insulating carrier section, wherein both the electrode section and the carrier section are made from a ceramic material. In order to improve the mechanical and electrical properties and in order to simplify the production, a green body of the carrier section and a green body of the electrode section are connected to each other, in particular materially, to form a single composite green body and are jointly sintered.
