PROBLEM TO BE SOLVED: To provide a liquid jet head which can suppress increase of numbers of input data lines without delaying a transmission time of data. ! SOLUTION: A print head 10a is equipped with an injection part 15, drive circuit substrates 11A, 11B, and a data conversion part 20. The data conversion part 20 transmits image data of m-bit inputted in series via a differential transmission line in synchronization with a shift lock of a second frequency, which comprises a frequency in which a shift lock frequency of a first frequency is multiplied by numbers of shift register parts, data after completion of transmission is parallel-serially converted, and is outputted in serial with respect to the shift register parts of the drive circuit substrates 11A and 11B. !
