PROBLEM TO BE SOLVED: To provide a method of driving a liquid jet head which is capable of selectively jetting liquid droplets from a predetermined nozzle, while increasing the driving frequency and to provide a liquid jet apparatus. SOLUTION: When a main piezoelectric element 301 is driven so as to jet liquid droplets from a predetermined nozzle 21, a driving signal which is in opposite phase to a driving signal to be applied to the main piezoelectric element 301 is applied to sub piezoelectric elements 302 and 303 corresponding to sub pressure chambers 12b and 12c communicating with a nozzle 21, which does not jet liquid droplets, to selectively jet liquid droplets from a predetermined nozzle 21.
