A liquid storage container includes a storage chamber that stores a liquid, a filter chamber that is provided with a filter and receives the liquid from the storage chamber to filter the liquid by the filter, and a partition wall that separates the storage chamber and the filter chamber. The partition wall is provided with a communication hole structure that allows the storage chamber and the filter chamber to communicate with each other. A shape of one or more openings of the communication hole structure in the storage chamber is a shape in which a distance from a center of gravity of an entirety of the one or more openings to the closest point in a contour defining the one or more openings is smaller than a radius of a circle having the same area as an area of the entirety of the one or more openings.
