A liquid ejecting apparatus including an ejector configured to eject a liquid with displacement of a piezoelectric element, a generator configured to generate a driving signal, which has a first waveform, for displacing the piezoelectric element in a first direction, and a second waveform, for displacing the piezoelectric element in a second direction opposite to the first direction, and a detector configured to detect a vibration remaining in the ejector in a detection time period starting after completion of the second time period. The difference between a duration from the first time point to the second time point and a duration that is a natural number times the period of a vibration produced in the ejector is shorter than one quarter times the period of the vibration produced in the ejector.
