ABSTRACT:
An ink cartridge has a storage space that receives a porous material for absorbing ink and having a pair of side walls opposed to each other, a first cover member, and a spacer member projecting from the first cover member into the storage space so as to occupy a predetermined space, the spacer member having an outer circumferential wall, a bottom wall and a support wall, the outer circumferential wall extending substantially along an inner surface of the storage space in section, the bottom wall covering a porous-material-side end portion of the outer circumferential wall, the support wall extending in a direction crossing the pair of side walls of the casing to be connected to inner surfaces of two sides of the outer circumferential wall. A space surrounded by the outer circumferential wall is made open to the outside through an opening portion formed to penetrate the first cover member.
