The present paper describes the results obtained by measuring the d.c. electric resistance between the separated electrodes prepared by vacuum deposition on the sodium copper?chlorophyllin films with respect to the relative humidities. The relative humidity?d.c. electric resistance curves were affected with electrode materials and intervals, but independent of the thickness of sodium copper?chlorophyllin films. And also these curves did not show the hysteresis loops with humidity cycles, even if the electrode materials and intervals were changed, but come to show the hysteresis loop as the film thickness increased. For the film with a given thickness, the values of d.c. electric resistance were higher in the order Al, Cu, Au and Ag when electrode material?d.c. electric resistance relationships were investigated at a constant electrode interval. This order seems to agree with the electrochemical series.
