To achieve such operations, the liquid ejecting head includes, in its liquid chamber, a first electrode placed so as to cover a heating resistor, a second electrode placed at a position different from that of the first electrode, and a third electrode.

In a case where the heating resistor is not driven, a voltage is applied between the second electrode and the third electrode so that the second electrode has the same polarity as that of the predetermined component, and the third electrode has the opposite polarity.
