Provided is an inkjet recording device capable of automatically setting an optimal excitation voltage for a piezoelectric element so that ink droplets are formed in a wide range of usage environment temperatures.　This inkjet recording device comprises: an excitation voltage circuit that applies an excitation voltage to a piezoelectric element provided to an ink nozzle; and a controller that performs setting of the excitation voltage. A liquid level sensor made of a rod-shaped conductive material and a GND terminal made of a rod-shaped conductive material are arranged inside a main ink container. A liquid level height of ink in the main ink container 10 is detected by measuring a terminal voltage between the liquid level sensor and GND. Ink viscosity is controlled by fine-tuning the liquid level height according to an ambient temperature. In a case where the ambient temperature is no more than 30℃, the inkjet recording device sets the excitation voltage so that printing is performed using an excitation voltage with which the ink column is shortest, and in a case where the ambient temperature is 30℃ or more, the device sets an excitation voltage so that, after raising the ink viscosity to a higher viscosity, printing is performed in a range of ±30% of the excitation voltage with which the ink column is shortest. Due to this configuration, the device is capable of automatically setting the excitation voltage within a wide temperature range.
