ABSTRACT:
A solid pole oxygen sensor wherein an oxygen sensor element is composed of a solid pole with one end of a lead wire buried therein; an internal electrode formed on the outside surface of the solid pole; a solid electrolyte enclosing the electrode to constitute a solid pole assembly as a column with a projection at its top; and a platinum electrode separated from the lead wire. The oxygen sensor element is so secured to an almost cylindrical ceramic insulator by means of adhesive or the like that the upper top side of the oxygen sensor element having the projection is matched to a recess at the tip of the cylindrical ceramic insulator and a pair of electroconductive zones provided on the side wall of the cylindrical ceramic insulator are electrically connected with the platinum electrode and the lead wire. A process of manufacturing a solid oxygen sensor is also disclosed.
