To provide a simple, safe and highly accurate apparatus for creating distribution image of electric conductivity and a visceral fat measuring apparatus by achieving impedance CT method to measure biological impedance of a subject with high accuracy.
Two pairs of electrode groups (51a and 51b) are located in a circular pattern on the outer periphery of the subject to be measured. Electric current is applied between two electrodes (Ai and Ai+2) which are sequentially selected from a first electrode group (51a), and potential differences between adjacent electrodes at the electrodes (Bi and Bi+2) corresponding to the two electrodes on which the electric current is applied among the remaining electrodes (A1, ..., Ai-1, Ai+1, Ai+3, ..., AN) of the first electrode group and a second electrode group (52b) are measured sequentially. Since the potentials at all electrode locations are measured, measurement error is compensated and highly accurate biological impedance measurement can be achieved.
