PROBLEM TO BE SOLVED: To provide an electric conductivity measuring instrument enhanced in meaurement precision, and to provide a soil conductivity measuring method and an instrument for measuring an electric conductivity of a soil solution enhanced in measuring precision using the electric conductivity measuring instrument.;SOLUTION: Current routes (34, the first current route 44, the second current route 46) formed by power supply side electrodes (8, 10, the first electrode 38, the second electrode 40, the third electrode 42) in a measured object (soil 2) are limited in a specified range, voltages are taken out from the current routes by detection side electrodes 12, 14, 48, 50, an influence caused by a foreign matter 36 comprising an insulator and a good conductor contained in the object is evaded to enhance the precision of the electric conductivity, and the measuring precision in the method of measuring the electric conductivity of the soil solution is enhanced by using a measured value therein.;COPYRIGHT: (C)2001,JPO
