 note = {application/pdf, The author previously reported on a Sodium Copper-Chlorophyllin (NaCuCph) film hygrometer, which was prepared by spreading NaCuCph solution on frost-glass and drying it at room temperature. However this type of hygrometer has generally a low electric resistance in the range of relative humidity from 40％ to 90％, and also has poor restorability, persistence and stability. The humidity sensor with Tetrapanax Papyrifer paper used in this work was prepared by immersing Tetrapanax papyrifer paper 1 mm thick into 1.5 wt. ％ NaCuCph solution and drying it at room temperature To measure the electric resistance of this sensor the paper was sandwiched with brass-meshes. This is a Tetrapanax papyrifer paper hygrometer. The electric resistance of this hygrometer was measured in the range of relative humidity from 40％ to 90％. This report represents that a Tetrapanax papyrifer paper hygrometer containing Sodium Copper-Chlorophyllin is useful to measure relative humidity, and improves the above described several weak points of Sodium Copper-Chlorophyllin film hygrometers.},
