A liquid ejecting head includes a nozzle opening that is formed on one face of a silicon substrate, and ejects liquid, a first concave portion that is provided on the other face of the silicon substrate, and configures a pressure generating chamber which communicates with the nozzle opening, and a second concave portion that is provided on one face of the silicon substrate, and configures a flow path which communicates with the first concave portion and supplies the liquid, in which the first concave portion and the second concave portion overlap each other in an in-plane direction when seen in a direction which is orthogonal to the face of the silicon substrate.
