At least, it has with one conductive electrode section and one insulated backing section, the arrangement of electrode of the electric surgical instrument where both of the electrode section and the backing section consist of the ceramic material is known. Machine quality and electric quality are improved, manufacturing method in order to simplify, the not yet calcination body of the backing section and the not yet calcination body of the electrode section are connected mutually, especially material and form one compound not yet calcination body, are sinterred when that has connected.少なくとも1つの導電性電極部と、1つの絶縁性支持体部とを備え、その電極部と支持体部の両方がセラミック材料から成る電気外科器具の電極装置が知られている。機械特性および電気特性を改良し、製造法を簡易化するために、支持体部の未焼成体と電極部の未焼成体が相互に、特に材料的に接続されて1つの複合未焼成体を形成し、それが連結した状態で焼結される。
