A humidity-sensitive element comprises a humidity-sensitive body which includes 21-73 mol % of Cr.sub.2 O.sub.3, 25-55 mol % of at least one member selected from the group consisting of ZnO and MgO, 0.5-8.0 mol % of CuO, 0.5-8.0 mol % of Li.sub.2 O, and 0.5-8.0 mol % of V.sub.2 O.sub.5, and a pair of electrodes attached to the body. Such an element provides excellent stability over a wide range of humidity and temperature levels.

Humidity-sensitive resistive element

A humidity-sensitive element which has excellent humidity-sensitive characteristics and has a small drift after being exposed to a high humidity for a long period of time. The humidity-sensitive element of the invention includes a porous metal oxide sintered body, a simple substance or an oxide of phosphorus or sulfur carried on the porous metal oxide sintered body, and copper ions carried on the porous metal oxide sintered body.
