<p>PROBLEM TO BE SOLVED: To provide a liquid injection head and a liquid injection recording device capable of thinning the thickness of an area on the opposite side to a liquid discharging side of a head chip, and improving assembling workability.SOLUTION: A liquid injection head comprises: a discharging portion 70 laminated with a first head chip 73a and a second head chip 73b; a circuit substrate 82 for outputting a driving signal for driving the discharging portion 70; a first connection substrate 83 electrically connecting the first head chip 73a and the circuit substrate 82; and a second connection substrate 84 electrically connecting the second head chip 73b and the circuit substrate 82. The circuit substrate is provided with a bending portion 85, and by bending the circuit substrate from the bending portion 85, a first electrode terminal portion 83a and a second electrode terminal portion 84a are drawn in the same direction, and opposed to each other in a laminating direction of the first head chip 73a and the second head chip 73b.</p> |
