Gas sensor and method for production thereof.

摘要

A gas sensor is constructed of a ceramic substrate (1), supporting heating elements (2) on a surface. The heating elements (2) are covered by an insulating layer (3) on which electrodes (6) are supported. The electrodes (6) are in contact with a gas sensitive catalyst layer (8) to detect electric current induced therein. The performance of the sensor is enhanced by the improved electrode heating of this construction while manufacture is improved.
