An ink cartridge has an ink pack that holds ink and a case that holds the ink pack. The case has a case body forming an ink pack storage space R, and a cover that is removably attached to the case body. An ink supply opening is formed in the front wall of the case body, and a body-side pedestal protruding from the interior of the case body toward the cover inside the case is formed at the opposite end as the ink supply opening. When the cover is attached to the case with an ink pack inside, the back end part of the ink pack is held between a cover-side pedestal protruding from the interior of the cover and the body-side pedestal. The back side of the body-side pedestal forms an exterior recess on the case that can be used as a fingerhold.
