A liquid ejecting head includes: a circuit board extending in a first direction and having a first surface and a second surface opposite the first surface in a second direction perpendicular to the first direction; a main body including head units; wiring members each extending from each head unit toward the circuit board; contacts including a first contact and a second contact connected to corresponding wiring members; a first support member facing the first surface; and a second support member facing the second surface. The first support member has a first protrusion protruding toward the first surface in the second direction and arranged at a position aligned with the second contact in the second direction. The second support member has a second protrusion protruding toward the second surface in the second direction and arranged at a position aligned with the first contact in the second direction.
