Humidity sensitive ceramic resistor having a high humidity activity, a low electrical resistance and a high stability with respect to time, temperature, humidity and electric load and suited for use in humidity-controlling devices is provided by a sintered mixture of a main component, which consists essentially of chromium oxide and at least one metal oxide selected from the group consisting of TiO2, ZrO2, HfO2, SnO2, Nb2O5, Ta2O5, WO3, MnO2, MoO2, CeO2, DyO2, VO2, SiO2 and GeO2, and an addition of at least one metal oxide selected from the group consisting of BeO, MgO, CaO, SrO, BaO, FeO, NiO, CuO, ZnO, CdO and PbO. Furthermore, humidity sensitive thin layer ceramic resistor having an improved quick response to humidity is obtained by sintering a mixture having the above composition with a glass frit binder.
