Abstract: An impurity detection support device includes: a pipe in which a liquid under test flows; a first electrode and a second electrode provided in the pipe, the first electrode and the second electrode being arranged such that an AC voltage is adapted to be applied to or an AC current is adapted to be superimposed on the liquid under test in a space extending between a first position and a second position; a power supply unit that applies an AC voltage or superimposes an AC current between a pair of electrodes; a measurement unit that measures a current or a voltage generated between the pair of electrodes; and a calculation unit that calculates a resistance of the liquid under test using a measurement result of the measurement unit.
