    摘要： An ink cartridge (20) includes a housing (70) that has an air communication port (70c) and stores a liquid inside and a sealing member (71) attached to the housing (70) in such a way as to cover the air communication port (70c). The sealing member (71) includes an adherent region (71a) attached to the housing (70) and a non-adherent region (71b) not attached to the housing (70). The non-adherent region (71b) extends to an end portion of the sealing member (71) and forms a communication passage which establishes communication between the air communication port (70c) and air.
