ABSTRACT:
A moisture sensitive element having on an insulating substrate a moisture sensitive section that changes its electrical resistance according to the humidity of atmosphere. The moisture sensitive section is prepared by mixing a polymerized organic silicon compound with particles of a moisture sensitive, electrically resistant material, applying a coat of the resulting blend onto the insulating substrate, and sintering the coat. The element is strong, has good moisture sensitivity characteristics and can be used for an extended period with little decrease in the moisture sensitivity and little change in the value of resistance.
