Abstract
An ink cartridge for use in a printer includes a second ink chamber in which a liquid can be stored, an ink flow path that leads the ink to an ink supply port through which the ink is supplied from the second ink chamber to outside, and a prism unit disposed in the ink flow path configured to detect an amount of the ink inside. A portion of the ink flow path downstream of the prism unit is defined by a first wall and a first seal film, and the first wall is lower than a second wall constituting the second ink chamber.
