We made the electrophotography which is able to visualize the distribution of electroconductivity to the skin.
According to an electric quantity, reducing KI into iodine, we got a compound of AgI with galvanochemical response and took a picture of a galvanic skindistribution on it. We may be able to apply both the A. C. and the D. C. in power supply. In order to take a good picture of electroconductive points, we used 12V of the D. C.. In this case, an electric quantity was
