A liquid cartridge includes a cartridge body; a liquid supply portion, an air flow path and a valve for opening and closing the air flow path. The air flow path is in communication with a liquid chamber through a communication hole and in communication with ambient air. The valve includes a valve main body and a sealing member provided on the valve main body. The valve main body includes a first opening, a second opening and an air passage connecting therebetween inside the valve main body for permitting air flow therethrough The sealing member includes a first elastic portion for sealing the communication hole and a second elastic portion in contact with an inner peripheral wall defining the air flow path to partition an internal space of the air flow path into a first chamber in communication with the first opening and a second chamber in communication with the second opening, the second elastic portion being configured to prevent liquid flow between the first chamber and the second chamber. |
