PROBLEM TO BE SOLVED: To provide an ink jet head capable of minimizing variation of a piezoelectric property of a piezoelectric substrate, reducing variation of drive voltage and discharge speed and stabilizing a discharge property. SOLUTION: A head chip 10 includes the piezoelectric substrate 1 having a plurality of first individual ink grooves 31, a plurality of second individual ink grooves 32 and a separation groove 14. Thus, only by applying groove treatment on the piezoelectric substrate 1 by a dicing machine, a configuration wherein a first head 10a including the first individual ink grooves 31 and a second head 10b including the second individual ink grooves 32 are formed on the one piezoelectric substrate 1 can be obtained.
