| 1. A liquid ejection apparatus comprising:
a plurality of energy-generating units secured to a base member;
a member having a plurality nozzles with ejection holes for ejecting the liquid which is pressurized by a corresponding energy-generating
unit and wherein a liquid-flowing space is provided between the base member and the member in which the nozzles are formed
and a plurality of support members which maintain a height of the liquid-flowing space; and
wherein a volume of space within each of the nozzles is substantially greater than a volume of space defined by the height
of the support members in a region directly above each of the energy generating units.
