Liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• a liquid ejecting head including a nozzle and configured to eject a liquid from the nozzle;
• a signal output part including an electrode and configured to output a signal in accordance with an electric change in the electrode in a case that the liquid is ejected from the nozzle;
• and
• a voltage applying circuit including a plurality of charge pumps connected in series, the plurality of charge pumps each including a capacitor and a diode and configured to boost a voltage, the voltage applying circuit being configured to apply the voltage boosted by the plurality of charge pumps to the liquid ejecting head or to the electrode, so that a potential difference between the liquid ejecting head and the electrode is generated,
• wherein the capacitor included in each of the plurality of charge pumps is independent from a capacitor component of the liquid ejecting head.
