Liquid ejecting head and liquid ejecting apparatus with improved mechanical strength
A liquid ejecting head includes a pressure chamber substrate in which a pressure chamber space is formed, a flow path substrate having a first surface on which the pressure chamber substrate is installed and a second surface that is on the opposite side to the first surface, and in which a first space, a supply hole that enables communication between the first space and the pressure chamber space, and a communication hole that communicates with the pressure chamber space are formed, a nozzle plate that is installed on the second surface and in which a nozzle that communicates with the communication hole is formed, a second space that is installed on the first surface and that communicates with the first space of the flow path substrate, a housing unit in which an opening portion that communicates with the second space is formed, a compliance unit that is flexible and installed on the second surface and that seals the communication hole and the first space, and a beam-like portion that extends between inner wall surfaces of the second space in the housing unit.
