Provided is a new method for controlling ion conductivity using a polymer solution that dissolves in an organic solvent at a low temperature to form a transparent solution, and undergoes phase separation when the temperature increases, more specifically, using a temperature-responsive polymer that undergoes lower critical solution temperature (LCST)-type phase separation. This method for controlling ion conductivity changes, according to the temperature, the ion conductance of a temperature-responsive ionic solution which contains a temperature-responsive polymer, a salt, and an organic solvent, and in which the salt is dissociated into ionic components. Preferably, the temperature-responsive polymer is a polymer that exhibits lower critical solution temperature-type phase separation.
