Abstract
A liquid ejection apparatus includes a liquid ejector, a resin-made liquid container, a resin-made reference container, a first electrode pair, and a second electrode pair. The liquid ejector is configured to eject liquid. The liquid container defines a space storing liquid to be supplied to the liquid ejector. The liquid container is configured such that a remaining amount of liquid therein changes due to an ejection operation of liquid by the liquid ejector. The reference container defines a space in which no liquid flows to the liquid ejector or from the liquid ejector. The first electrode pair is provided to correspond to the liquid container. The second electrode pair is provided to correspond to the reference container.
