A method for managing a thickness of a multilayered body constituting a part of a liquid-ejecting head, wherein the liquid-ejecting head includes: (a) a liquid-channel unit formed of plate members laminated on each other with at least one adhesive layer each interposed between adjacent ones of the plate members, the liquid-channel unit including a liquid channel provided in an inside thereof and a nozzle provided in an outer surface thereof; and (b) an actuator fixed to the liquid-channel unit and operable to eject liquid from the nozzle, wherein the multilayered body constitutes at least a part of the liquid-channel unit, and includes plate members as at least a part of the plate members constituting the liquid-channel unit and at least one adhesive layer as at least a part of the at least one adhesive layer constituting the liquid-channel unit, and wherein the thickness of the multilayered body is managed to be not less than a sum of (i) a total thickness of the plate members constituting the multilayered body and (ii) a product in which a reference thickness as a minimum required thickness of one of the at least one adhesive layer is multiplied by a number of the at least one adhesive layer constituting the multilayered body. |
