The opening communicates with the ink reservoir through a fluid path. The cartridge further includes a stop to be tightly fitted in the opening. The stop has an elasticity, and is configured such that a hollow needle can be penetrated therethrough. A hole formed on the stop by penetration of the hollow needle is closed by the elasticity of the stop after removal of the same. A valve structure is provided to a part of the stop, the valve structure selectively opens and closes the communication between the opening and the ink reservoir through the fluid path.
