Abstract
There is provided a liquid storage container capable of keeping a negative pressure therein more reliably. An ink cartridge includes a negative pressure generation unit configured to generate a negative pressure in an ink storage chamber and a filter attached to an atmosphere communication channel opening and allowing air to pass from the outside to the inside of the liquid storage chamber depending on the negative pressure in the ink storage chamber. The ink cartridge has a capillary groove configured to supply ink from a portion in which ink is stored in the ink storage chamber to the filter.
