A liquid ejecting apparatus includes a liquid ejecting head that is driven by a first drive signal to eject a liquid, an analog conversion circuit that converts a digital first waveform signal designating a waveform of the first drive signal into an analog second waveform signal designating the waveform of the first drive signal, a first transistor pair that includes two bipolar transistors generating the first drive signal based on the second waveform signal, a first cooling mechanism that cools the first transistor pair, and a second cooling mechanism that cools the analog conversion circuit.
