There is provided a liquid discharging apparatus including: a modulation portion which generates a modulation signal pulse-modulated from a source signal; a gate driver which generates an amplification control signal based on the modulation signal; a transistor which generates an amplification modulation signal amplified from the modulation signal based on the amplification control signal; a low pass filter which demodulates the amplification modulation signal and generates a driving signal; a piezoelectric element which is displaced as the driving signal is applied; a first power source portion which applies a constant voltage signal to a terminal which is different from a terminal to which the driving signal of the piezoelectric element is applied; and a temperature detection portion which detects temperature, in which the first power source portion is disposed on the shortest straight path between the temperature detection portion and the gate driver.
