PROBLEM TO BE SOLVED: To respectively independently extract and provide a value for which the impedance of a body end tissue peripheral part is included in the contact impedance of an electrode and a body end tissue skin surface together with the value of a conventional intra-body impedance. SOLUTION: A current path having finite electric conductivity is formed by connecting a resistor r1 between at least two electrodes E2 and E3 among a plurality of the electrodes E1-E4 in direct or indirect contact with the body skin surface at the two parts of the body skin surface. A measuring circuit is constituted so as to make both electrodes apply a current at least once in a measuring process. |
