Abstract
A liquid ejecting apparatus includes a liquid discharging head having a nozzle and a piezoelectric element, a driving signal generating circuit, a reference voltage signal generating circuit, a substrate on which the driving signal generating circuit and the reference voltage signal generating circuit are provided, a first wire, a second wire, and a coil, in which the driving signal generating circuit generates a driving signal, the reference voltage signal generating circuit generates a reference voltage signal, the piezoelectric element is driven based on the driving signal supplied to one end of the piezoelectric element and the reference voltage signal supplied to the other end of the piezoelectric element, the first wire propagates the driving signal to the one end, and the second wire propagates the reference voltage signal to the other end through the coil.
