In this paper a biological three‐medium spherical model which consists of tissue, its membrane, and the extratissue medium is employed, and detailed distributions and characteristics of the induced current in the modeled structure are calculated by using a semianalytical solution developed for this model. It is demonstrated that both the change in the thickness and electrical properties of the biomembrane and the difference in conductivity between the inner and outer substances significantly affect the current passing through the membrane and the resultant profiles of the induced current. These analytical results are consistent with the experimental results, suggesting the influence of real membranes, and they indicate an important influence of the biomembrane on the induced current characteristics under specific membrane conditions. © 2001 Scripta Technica, Electr Eng Jpn, 135(2): 17–25, 2001
