A solid pole oxygen sensor in which one end of a lead wire of platinum or platinum/rhodium is buried in a solid pole and the surfaces of the solid pole and the lead wire are coated with an electroconductive paste. The solid pole is wrapped or encased in a solid electrolyte, pressure-molded into a pellet, which is dried and then fired in a reducing atmosphere. The surface of the sintered mass thus obtained is then plated or baked to form a platinum electrode, and the oxygen sensor element thus obtained is fitted or secured to the tip of an approximately cylindrical ceramic insulator equipped with electroconductive zones to be connected to the platinum electrode. |
