ABSTRACT:
A moisture sensitive device includes a polymer capacitive moisture sensitive element and a heater. The polymer capacitive moisture sensitive element is formed by sequentially stacking a lower electrode, a moisture sensitive film made of an organic polymer resin material, and an upper electrode on an insulating substrate. The heater serves to heat the moisture sensitive film to restore the original characteristics thereof.
