Abstract

PURPOSE:To make a continuously varying output characteristics for the concentration of oxygen at a region of diluted side for a logical air-fuel ratio, by covering a titania thick film by mixed coating of catalyst-catalyst poison. CONSTITUTION:A thermistor ceramic film 2 varying a resistance relating to a temperature of waste gas, is formed on the surface of an alumina substrate 1. This film 2 is provided as a temperature compensation, and the same material to an oxygen concentration responsive, film 11 is used. The first-third platinum electrode films 3-5 are formed on the substrate 1 separately to each other and the film 2 is allowed to contact with the films 3, 4. The titania thick film 11 i.e. oxygen concentration detection film is formed contacting with the films 4, 5. A coating 12 of mixture of unburnt oxidation reaction accelerating catalyst composed of one or both of platinum and palladium and catalyst poison composed of >=1 kinds of lead, sulfur, arsenic, halogenide, is formed so as to cover the whole free surface of the film 11.
