PROBLEM TO BE SOLVED: To provide an electric characteristic measuring system which continuously measures the electric characteristics of a physiological body, such as a bioelectric impedance, at a high speed. SOLUTION: A measuring signal generator 72 generates a probe current Ia (measuring signal), and transmits the probe current Ia to the body B of a subject through surface electrodes Hc and Lc which are conductively attached to surface areas at specified two locations being separated from each other on the body B of the subject. An I/V converter 91 measures an electric current value of the measuring signal which is transmitted to the body B of the subject. A differential amplifier 81 measures an electric voltage value which is generated between the surface areas at the specified two locations being separated from each other on the body B of the subject. A CPU 3 calculates the electric characteristics between the surface areas of the subject from the current value and the voltage value which are respectively measured by the I/V converter 91 and the differential amplifier 81 or the like. Especially, the measuring signal generator 72 continuously transmits the measuring signal to the subject from the completion of the this-time measurement by the I/V converter 91 and the differential amplifier 81 or the like to the start of a next measurement. |
