Abstract
PURPOSE:To enable to sufficiently fit for use even under a severe condition, by impregnating and coating the base body with glass from the upper face of either protective layer or catalyst layer of an oxygen sensor element used for exhaust gas purification system, etc. CONSTITUTION:The electrodes 2, 3 made of platinum etc. are formed on both sides of the base body of oxygen sensor 1. The protecting layer 4 made of alumina, etc. is formed on the outside electrode 3 of the body 1 and the catalyst layer 6 is additionally formed if required. The glass coated film 5 is formed by applying pasty glass on the upper face of the layer 4 or 6. In such a condition, the glass is brought to melt by heating at a temperature higher than melting point of the glass and is made permeated into the porous body 1 through the layers 6, 4 and electrode 3. By said method, the element of oxygen sensor having a sufficient durable strength even when it is exposed to repeating severe heating cycle and also, having a superior sensitivity, is obtained.
