A liquid ejecting head includes a plurality of stacked substrates that include a nozzle substrate having a nozzle from which liquid is ejected. A channel is formed in at least a part of the substrates and guides the liquid to the nozzle. The channel includes: a first channel that extends in an X direction intersecting a stacking direction in which the substrates are stacked; a curved section curved in a Z direction that intersects the X direction and contains a component of the stacking direction; and a second channel that extends from the curved section in the Z direction. A wall is formed in a corner portion inside the channel so as to intersect both the X and Z directions, and the corner portion is formed in the curved section between the inside walls of the first and second channels.
