A liquid tank comprising: an absorption chamber containing an absorber absorbing and holding the liquid; a liquid outlet disposed on a bottom surface of the absorption chamber in usage of the liquid tank, and configured to supply liquid to a liquid discharge recording head; a pressure contact body disposed between the absorber and the liquid outlet such that the pressure contact body contacts the absorber; a liquid chamber directly holding the liquid supplied to the absorption chamber; a partition configured to separate the liquid chamber and the absorption chamber, the partition including a communication part, by which the liquid chamber communicates with the absorption chamber, on the bottom surfaces of the absorption and liquid chambers; and a liquid-guiding path extending from the bottom surface of the liquid chamber to the bottom surface of the absorption chamber, a distance between an end of the liquid-guiding path on the side of the absorption chamber and an edge of an upper surface of the pressure contact body being smaller than a distance between a horizontal surface passing through an upper edge of the communication part and the upper surface of the pressure contact body.
