1. A liquid ejecting head comprising:
a channel substrate having a channel through which a liquid flows;
a nozzle substrate having a nozzle through which the liquid supplied through the channel is ejected in an ejection direction, the nozzle substrate being stacked on the channel substrate in the ejection direction;
the liquid ejecting head further comprising a plasma generator which includes a first electrode and a second electrode and in which an alternating voltage is applied to at least the first electrode to generate an atmospheric-pressure plasma around the first electrode, the atmospheric-pressure plasma accelerating the liquid ejected through the nozzle, wherein
the first electrode is disposed on a surface of the nozzle substrate in the ejection direction,
the second electrode is disposed opposite the first electrode in the ejection direction, and
the first electrode is farther than the second electrode from the nozzle in an intersecting direction intersecting the ejection direction.
