PROBLEM TO BE SOLVED: To provide a stable and semipermanent device and method for automatically distributing a transmission electrode that allows bipolar transmission high-speed switching. SOLUTION: This device for automatically distributing/controlling a transmission electrode of an electrical resistance survey measuring system comprises a circuit for connecting a pair of MOSFETs to the upper and the lower stages of each of n transmission electrodes, and interconnecting the pair of MOSFETs in parallel, and a controlling means for controlling ON/OFF of each MOSFET.
