Humidity response characteristics of BaTiO 3 doped with lanthanum were examined using complex impedance measurements. A sample with relative density of 71% showed a nearly log‐linear increase of conductivity with humidity at 118 Hz. The average capacitance of bulk changed little with humidity; however, the resistance showed a gradual decrease. The equivalent circuit explaining such an observation was presented.
