Abstract
A moisture sensitive element including a sheet made from a mixture of electrically insulating fibers having the property to expand upon adsorbing the moisture (e.g., cellulose fiber) and electroconductive fibers (e.g., activated carbon fiber). The moisture sensitive element is capable of sensing the humidity of the air by determining the electric resistance which varies according to the change of the humidity of the air, and can also be applied as a condensation sensor which can sense, for example, dew condensation on windowpanes.
