Abstract
A capacitive humidity sensor includes a pair of opposed electrodes on a substrate. A humidity-sensitive film covers the electrodes. The electrodes are comb-shaped and interdigitated. Humidity is detected based on the capacitance between the pair of electrodes, which changes with changes according to the humidity in the atmosphere. The uniform width of each tooth in the pair of electrodes is L , and the uniform distance between a tooth of one of the electrodes and a tooth of the other electrode is L . When L is less than 3 micrometers, L is 5 micrometers. When L is greater than or equal to 3 micrometers, L is less than or equal to 5 micrometers.
