A voltage is applied from the voltage source 11 between the second transparent conductive film 5 of the CD 12. By applying a negative voltage to the metal electrode 9 side and a positive voltage to the second transparent conductive film 5 side by the voltage source 11, EC

値が高くなっている事が分かる。The voltage applied at this time must be varied according to the resistance value specification of CM8, and it is estimated that the matrix cell 13 of the ECD 12 will have a maximum of about 1.5V. (This is because the ECD 12 is not destroyed.) When a voltage is applied, a voltage drop occurs according to the variation of the resistance value in the plane of the CM 8, and the matrix cell 13
The voltage value applied to is changed. If the measured object 8 is removed after the voltage is applied, each matrix cell 13 on the side of the first transparent conductive film 1 retains its color in a state in which the coloring state is different for each matrix cell 13 as shown in FIG. 2B. Figure 2 (B)
However, since the upper right portion and the lower left portion are deeply colored, the resistance value of this portion is low (that is, a high voltage is applied to the matrix element body 12 of the ECD 12) and the resistance values of other portions are high. I understand.

程度の物で十分である。As described above, the distribution of the resistance value of the CM 8 can be visually displayed. Also, by reversing the application of voltage, this phenomenon undergoes a reversible change and becomes transparent, so that it can be used repeatedly. It is generally said that the life of the ECD12 is about 10 5 times, so it can be said that repeated measurement of this level is possible. Further, it is possible to calculate the resistance value to some extent quantitatively by obtaining the correlation between the applied voltage and the applied time and the change in transmittance and preparing a color sample or the like. The thin film of the present invention can be formed by CVD (chemical vapor deposition) or PVD (physical vapor deposition) such as sputtering or vapor deposition. Regarding the size of the matrix element 13, the mask pattern may be appropriately determined according to the degree of dispersion of the resistance value of the CM 8 on the inner surface, but the mask pattern is about 3 to 5 mm □, and the distance between the patterns is 1 mm to 2 mm.

To avoid current leakage, it is desirable to reduce the mask opening area by several percent. Finally, a resist is applied on the upper portion using the same mask as when the cathodic layer 2 is formed.
