ABSTRACT:
A liquid ejecting head includes a reservoir forming substrate provided with a reservoir serving as a common liquid chamber; in which at least a portion of a wall surface of the reservoir is an inclined surface, a lower side of the reservoir in a vertical direction is provided with a lower portion of which a width is wider than an upper portion of the reservoir in the vertical direction thanks to the inclined surface, a compliance portion which absorbs pressure of the reservoir is disposed at an area which faces the lower portion and has a shape corresponding to the lower portion, and the reservoir communicates with an upper portion of each of the pressure generating chambers in the vertical direction rather than a lower portion of each of pressure generating chambers.
