An ink cartridge has a case in which is disposed a flexible ink bag containing ink. The ink bag has two opposed major surfaces, one of which is fixed to the case. Two regulation members are adhered to the other major surface and are spaced apart in the lengthwise direction of the ink bag to define therebetween a deformable region which extends the full width of the ink bag and along which the ink bag deforms as the ink is consumed and the ink bag contracts. An ink end detection plate is adhered to the other major surface, adjacent one of the regulation members, and undergoes movement with the ink bag as it contracts to provide an indication of when the ink is nearly used up.
