Abstract
A sintered body for a humidity sensor is formed by baking a blend at 1,000.degree. to 1,400.degree. C., the blend comprising ZnO, Cr.sub.2 O.sub.3, V.sub.2 O.sub.5 and M.sub.2 O where M.sub.2 O is at least one metal oxide selected from Li.sub.2 O, Na.sub.2 O and K.sub.2 O. A pair of electrodes are each attached to the corresponding surface of the sintered body to obtain a humidity sensor of metal oxide which is relatively low in its resistive value and stable in its aging characteristic.
