Abstract
The liquid ejection apparatus is capable of reducing the increase of the viscosity of a liquid due to evaporation of the liquid and also for reducing the quantity of the atmospheric air dissolving into the ink. A liquid seal used for a liquid ejection apparatus which performs recording by ejecting a liquid, at least a part of the liquid seal is formed from a layer compound mixture material including a high molecular compound and an inorganic layer compound. The liquid seal seals the liquid. For example, the liquid seal is an ink cartridge accommodating the liquid therein, or an ink guide member for supplying the ink in the ink cartridge to a recording head unit.
