IPC: G01N27/04
Filed: 2018-07-23
Abstract: To provide a gas sensor which suppresses deterioration in catalyst performance caused by temperature variation at each site of a catalyst, and restricts degradation of gas detection accuracy.SOLUTION: A gas sensor 1 for measuring a concentration of a component contained in a measured gas includes: a catalyst unit 2; a sensor element 3A; and a heater 5. The catalyst unit includes a base part, and a catalyst part. The base part includes: a plurality of partition wall parts; side wall parts; and partition wall connection parts. In the gas sensor, the base part includes the partition wall connection parts separately from the side wall parts, and therefore, not only the side wall parts, but also the partition wall connection parts function as a heat conduction path for connecting the plurality of partition wall parts together. Accordingly, heat conduction to partition wall parts at a position alienated from the heater becomes satisfactory, such that temperature variation in the whole base part is suppressed. Further, an activation state in the whole catalyst part becomes satisfactory, so that decrease of a chemical transformation amount of gas components contained in the measured gas can be restricted, and degradation of gas detection accuracy is restricted.SELECTED DRAWING: Figure 1
