摘要： A lithium ion-conductive glass film containing 20-80 mol% Li2O. It has a dense structure capable of shutting off a gas, and can be used as a solid electrolyte for a dioxide gas sensor. A thin carbon dioxide gas sensor characterized in that it includes this lithium ion-conductive glass film as a solid electrolyte. This sensor is capable of completely eliminating noise, which occurs due to the permeation of a gas therethrough, owing to the lithium ion-conductive glass film having a dense structure, and improving the accuracy of a measurement value of dioxide gas concentration. Since the lithium ion-conductive glass of this sensor is formed to a film structure, the internal resistance of the sensor is low, and the sensor is operated at a low operating temperature, and has a high response speed. Therefore, this sensor permits the use of a smaller heater than those used in the conventional sensor of this kind, and it becomes compact even when it is integrated with a heater. In the thin carbon dioxide gas sensor according to the present invention using an oxygen ion-conductive ceramic material for a substrate or a film, the oxygen ion-conductive ceramic material shuts off ions other than oxygen ions. Accordingly, the concentration of a carbon dioxide gas can be measured by inserting this carbon dioxide gas sensor as a whole into an object gas to be examined.
