摘要：To provide a liquid storage container that can prevent false detection of a liquid remaining-amount sensor by preventing air bubbles from reaching a detection position of the liquid remaining-amount sensor as long as a usable amount of liquid remains in liquid storage chambers even when the air bubbles enter liquid guide paths from the liquid storage chambers. The liquid storage container has a cartridge main body 10 that includes an upper ink storage chamber 370, a lower ink storage chamber 390, and a buffer chamber 430. The upper ink storage chamber 370 and the lower ink storage chamber 390 are connected to each other with an ink guide path 380 which provides a descending connection so that ink I descends downward therethrough. The lower ink storage chamber 390 and the buffer chamber 430 are connected to each other with an ink guide path 420 which provides an ascending connection so that the ink I ascends upward therethrough. Thus, the descending connection and the ascending connection are alternately provided so as to connect the ink storage chambers in series.
