A liquid ejecting apparatus includes an element substrate having thereon a plurality of heaters for generating energy for ejecting liquid; a plurality of liquid chambers provided on the element substrate and having ejection outlets for ejecting the liquid, wherein a plurality of the heaters are disposed in each of the liquid chambers, and wherein one part of the heaters and the other part of the heaters are switchably operable; and a switching unit for switching between a mode in which the one part of the heaters is actuated as main heaters, and the other part of the heaters stands by as stand-by heaters, and a mode in which the other part of the heaters is actuated as main heaters, and the one part of heaters stands by as stand-by heaters. A center of gravity of the one part of heaters and a center of gravity of the other part of heaters are aligned with each other in a plane of the element substrate, and surfaces of the heaters are protected by an anti-cavitation film comprising metal.
