Abstract
A moisture sensitive element in which a functional film is formed in contact with opposing electrodes arranged on a substrate. The element includes a mechanism for measuring the temperature of the functional film. The functional film has a porous structure made from a polymer material with hydrophilic properties and includes fine pores. A holding film is formed on inner walls of the pores and made from another polymer material having hydrophobic properties. An electrolytic salt is held within the pores.
