Claim:
1. A liquid ejecting head comprising: a nozzle plate made of a silicon single-crystal substrate and comprising holes; a substrate, wherein the nozzle plate is fixed to a first side of the substrate, the substrate comprising flow channels in communication with the holes; a flow channel formation substrate fixed to a second side of the substrate, wherein a surface area of the flow channel formation substrate fixed to the second side is smaller than a surface area of the second side of the substrate to which the flow channel formation substrate is fixed; a case defining a liquid holding portion in communication with the flow channels; and pressure generation units for ejecting liquid through the holes, wherein a surface area of a surface of the nozzle plate from which liquid is ejected is smaller than a surface area of the first side of the substrate to which the nozzle plate is fixed, wherein the surface area of the flow channel formation substrate is larger than the surface area of the nozzle plate.
