Claim:
A liquid ejection apparatus comprising: a plurality of energy-generating units secured to a base member; nozzles having ejection holes for ejecting a pressurized liquid, wherein one of said nozzles is disposed above each of the energy-generating units, and wherein first open sides of the nozzles which face the energy-generating units serve as liquid inlets and second open sides of the nozzles serve as the ejection holes, so that inner spaces of the nozzles serve as the liquid cells, the liquid cells not being provided separately; and wherein the energy-generating units are aligned on the base member generally in a row, and a plurality of support members arranged generally in rows adjacent the row in which the energy-generating units are aligned, and wherein an arrangement location with reference to the energy-generating units of the support members for a row closest to the energy generating units is different from an arrangement location with reference to the energy generating units for the support members in another row.
