Abstract (en)

[Object] To provide a liquid ejecting head in which unevenness of ejection can be reduced, and increased reliability of a wiring board can be obtained, and a recording apparatus which uses the liquid ejecting head. [Solution] A liquid ejecting head 2 which includes a flow path member 4 including pressurizing chambers 10 which are respectively arranged on the row and column at equal intervals, and a common flow path 5, and a piezoelectric actuator substrate 21 which includes a second electrode (individual electrode) 25. The common flow path 5 extends in the row direction, communicates with the pressurizing chambers 10 which align on both sides row by row, the second electrode 25 includes an electrode main body 25a, a first extraction electrode 25b-1 which is extracted from the electrode main body 25a in the first region 10-1 which is overlapped with the common flow path 5, and a second electrode 25b-2 which is extracted from the electrode main body 25a in the second region 10-2 which is not overlapped with the common flow path, any one of the two extraction electrodes is electrically connected to the wiring board 92, and the two extraction electrodes are alternately connected in the row direction.
