A flow channel member to which an ink cartridge is removably mounted has a sealing member made of an elastic material around the entire periphery of an installation section of a flow channel member main body. The sealing member is integrally formed of: a top plane portion, where an end face of a leg portion abuts the top plane portion so as to define an enclosed space between an inner peripheral surface of the leg portion and an outer peripheral surface of the installation section; and an inner leg portion and an outer leg portion extending from edges of the top plane portion along the longitudinal axis of the installation section, and having end faces, abutting the flow channel member main body. Furthermore, the sealing member has curved thicker portions. |
