PROBLEM TO BE SOLVED: To reduce a volume around first and second flexible substrates 3, 4, and simplify connection with an external circuit.SOLUTION: A liquid jet head 1 includes: a head part 2 having first and second channel arrays Ch1, Ch2; a driver IC 5 generating a drive signal; a first flexible substrate 3 which has a first terminal array 6a and a second terminal array 6b, and supplies the drive signal for driving the first channel array Ch1 to the head part 2 by electrically connecting the first terminal array 6a to the head part 2; and a second flexible substrate 4 which has a third terminal array 6c and a fourth terminal array 6d electrically connecting the third terminal array 6c, and supplies the drive signal for driving the second channel array Ch2 to the head part 2 by electrically connecting the third terminal array 6c to the second terminal array 6b of the first flexible substrate 3 and electrically connecting the fourth terminal array 6d to the head part 2.SELECTED DRAWING: Figure 1 |
