Abstract
An ink cartridge includes a housing that has an air communication port and stores a liquid inside and a sealing member attached to the housing in such a way as to cover the air communication port. The sealing member includes an adherent region attached to the housing and a non-adherent region not attached to the housing. The non-adherent region extends to an end portion of the sealing member and forms a communication passage which establishes communication between the air communication port and air.
