When the drive frequency of the piezoelectric body at which the liquid is ejected is defined as a first drive frequency, the coercive voltage of the piezoelectric body obtained when the piezoelectric body is driven at the first drive frequency is defined as a first coercive voltage, a drive frequency lower than the first drive frequency is defined as a second drive frequency, and the coercive voltage of the piezoelectric body obtained when the piezoelectric body is driven at the second drive frequency is defined as a second coercive voltage, the difference between the reference voltage and the minimum value of the drive voltage is higher than the first coercive voltage and is lower than the second coercive voltage.
