A humidity sensitive element, which comprises a sintered humidity sensitive resistor composed of 70 to 20 mole % of ZnFe.sub.2 O.sub.4 and 30 to 80 mole % of a member selected from the group consisting of SiO.sub.2 and MnO.sub.2 and can detect humidity as electrical signals due to the nature of the element that its electrical resistance varies with the change of the humidity to be detected.
