An ink cartridge (1) including: a casing (1a, 1b, 1c) having an ink chamber (20) for storing the ink; and a plurality of projections (R) projecting from an outer surface of the casing and spaced apart from each other. The plurality of projections (R) preferably includes at least three projections (R) which are arranged at substantially the same pitch (P). Each of the plurality of projections (R) is preferably provided by a projecting plate (R) which is elongated along the outer surface of the casing (1a, 1b, 1c). A height of each of the plurality of projections (R) is preferably is larger than a pitch (P) between each adjacent pair of the plurality of projections. The plurality of projections are preferably formed integrally with the casing. |
