The present invention provides a liquid ejecting head and a liquid ejecting apparatus which are excellent in operational reliability and discharge performance. The liquid ejecting head includes: a head chip (52A, 52B) having a discharge area formed by the discharge passages spaced apart in the X direction, and forming a drive electrode (61) in a driving wall that defines a discharge channel; flowpath members (51A, 51B) stacked on the head chip (52A, 52B) in the Y direction to form an ink flow path (81, 155) communicating with the discharge passage. In the X direction, an insulating sheet (135, 170) that joins the head chip (52A, 52B) and the flow path member (51A, 51B) via the adhesive (S1, S2) in a portion located outside the discharge area is disposed. In the X direction, the head chips(52A, 52B) and the flow path members (51A, 51B) are arranged separately in the Y direction at a portion located in the discharge region. 本发明提供工作可靠性及吐出性能优秀的液体喷射头及液体喷射装置。具备：头芯片(52A,52B)，其具有吐出通道沿X方向隔开间隔而形成的吐出区域，并且在限定吐出通道的驱动壁(61)
