るＯ２センサ。[Claims for Utility Model Registration] The outer and inner circumferential surfaces of a ceramic tube with a sealed tip are coated with an outer electrode band and an inner electrode band made of platinum. A disc-shaped contact plate is supported between the proximal end surface of the tube, and a lead wire connected to the contact plate is inserted through a rubber bushing closely attached to the other end of the cylindrical insulator. O made into
2 sensor, a disc made of a conductive material having approximately the same shape and dimensions as the contact plate is attached in close contact with the contact plate, and this disc is brought into contact with the proximal end surface of the ceramic tube. An O 2 sensor characterized in that the body and the inner electrode band are electrically connected.
