Abstract
PURPOSE: To secure the simple production of the moisture-sensitive element which features the excellent reproducibility and small hysteresis by making use of variation of the resistance value to the humidity of a specified polymer.
CONSTITUTION: A pair of comb-line electrode 2 and 2 are provided in opposition to each other on alumina substrate 1 to from gap 3, and then lead wire 4 and 4 are connected to electrode 2 and 2. Then the polymer solution of the reactive cationic monomer such as 2-hydroxy-3-methacryl oxy-propyl trimetyl ammonium chloride is coated and dried as if it covered over gap 3 on the moisture-sensitive element substrate. The polymer thin film thus formed is given the heat treatment in the dry atmosphere at 100°C or higher temperature to be burnt and fixed onto the substrate. The bridging process can be given to the polymer thin film in order to increase the anti-moisture performance of the moisture-sensitive element.
