A hydrophilic polymer material such as polyvinyl alcohol is formed into a porous film ( ). A film (holding film) ( ) made from a hydrophobic polymer material such as polyvinyl acetate is formed on the inner walls of a large number of pores ( ) formed in the porous film ( ). Lithium chloride ( ) is held in these pores ( ).

Moisture sensitive element and method of manufacturing the same

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.

A moisture-sensitive element includes a moisture-sensitive film consisting of a polymer prepared by polymerizing a methacrylate monomer not having a hydroxyl group. A humidity detector using the moisture-sensitive element is also disclosed.
