PROBLEM TO BE SOLVED: To independently calculate the contact impedances between electrodes and the surface of the skin of the body and the internal impedance between the skin, which comes into contact with the electrodes, and the skin. SOLUTION: A plurality of electrodes E1-E4 provided so as to come into contact with the surface of the skin of the body are held to always measurable electric conductivity so that a current flows to the contact parts of the electrodes with the surface of the skin of the body to measure the potential drop generated in the contact parts and, in this state, the voltages between the electrodes are measured by a measuring means to independently calculate the impedances X, Y, Z and U of the contact parts and the internal impedance M. |
