Zusammenfassung:	To provide an ink storage container in which aqueous ink is contained, generation or proliferation of fungi is effectively suppressed, and clogging of a filter or the like at the time of filtration is hard to occur.SOLUTION: An ink storage container (ink cartridge 30) includes an aqueous ink (ink 20) and a container body (ink cartridge body 28) containing the aqueous ink (ink 20) therein. The aqueous ink contains a color material and air bubbles formed of gas such as oxygen gas, nitrogen gas, or air. The ratio (%) of air bubbles having a particle diameter of 500 nm or smaller with respect to all the air bubbles, is 50% or more based on the number.SELECTED DRAWING: Figure 1 【課題】菌類の発生又は増殖が有効に抑制され、ろ過時におけるフィルターなどの目詰まりが発生しにくい水性インクが収容されたインク収容容器を提供する。【解決手段】インクジェット用の水性インク（インク２０）と、水性インク（インク２０）をその内部に収容する容器本体（インクカートリッジ本体２８）とを備えるインク収容容器（インクカートリッジ３０）である。水性インクが、色材、及び酸素ガス、窒素ガス、空気などの気体で構成される気泡を含有し、気泡の全体に占める、粒子径５００ｎｍ以下の気泡の割合（％）が、個数基準で、５０％以上である。【選択図】図１
