There is provided a capacitive load driving circuit connected to a capacitive load that causes ejection, from an ejecting nozzle, of a liquid droplet of a droplet amount that corresponds to a voltage level of charging voltage, the capacitive load driving circuit including: a first line that is connected to the capacitive load and that applies the charging voltage to the capacitive load; a power source line carrying dc voltage that is supplied from a power source for driving of the capacitive load; a charging control signal line that controls a voltage level of the charging voltage with respect to the capacitive load; and an N-type electric field effect transistor to whose source the first line is connected, and to whose drain the power source line is connected, and to whose gate the charging control signal line is connected.
