Abstract: A base fluid for heat medium contains a hydrophilic ionic liquid and water. A molecular weight of the hydrophilic ionic liquid is at or below 150. The hydrophilic ionic liquid is methylammonium nitrate. Since the ionic liquid has favorable thermal stability, the thermal stability of the base fluid for heat medium can be secured. Since the molecular weight of the hydrophilic ionic liquid is at or below 150, the base fluid for heat medium has a low kinematic viscosity. Further, since the freezing point depression effect can be obtained by dissolving the ionic liquid in water, a low freezing point can be realized.
