Abstract

A method for manufacturing a sensing element is provided, in particular for determining the oxygen content in exhaust gases of internal combustion engines, a composite construction having at least one ceramic paste (green film) present in film form being sintered to yield the sensing element, and sharp edges of the sensing element being blunted before sintering to increase the thermal shock resistance of the sensing element.
