Abstract
A liquid discharging apparatus includes a first piezoelectric element that includes a pair of electrodes including a first electrode and that is displaced according to a potential change of a driving signal in a case where the driving signal is supplied to the first electrode, a reference piezoelectric element that includes a pair of electrodes including a reference electrode, an internal space of which a volume changes in response to displacement of the reference piezoelectric element, and a detecting unit that detects a potential of the first electrode via a first wire and detects a potential of the reference electrode via a second wire in a first detection period which is a period after the first piezoelectric element is displaced due to the driving signal, in which the internal space is not filled with the liquid.
