Abstract: A liquid ejecting head includes an ejection surface which extends in a first direction (X-direction) and on which a plurality of nozzles ejecting a liquid are distributed; and protrusion sections that are formed on the ejection surface and protrude on a liquid ejection side in which the liquid is ejected. The ejection surface has abutting regions on which a sealing body that seals the plurality of nozzles by surrounding the plurality of nozzles abuts. When projecting the abutting regions and the protrusion sections along a first direction (X-direction) on a virtual line along a second direction (Y-direction) intersecting the first direction, the protrusion sections are disposed on the ejection surface such that projection of the protrusion sections crosses a boundary of projection of the abutting regions.
