To provide a refillable container enabling that a refilling operation is easily performed when a liquid content is used up, that an inner container configured to store the liquid content is resource saving, and that an outer container is used repeatedly even at a place where the outer container is liable to be wetted, the refillable container includes an outer container (3), a lid member (4), an inner container (5), and a pump (6). The outer container (3) has an opening (2) formed in an upper part thereof, and is made of plastic. The lid member (4) is configured to close the opening (2) of the outer container (3) and is made of plastic. The inner container (5) is made of paper, configured to store the liquid content therein, and replaceably accommodated in the outer container (3) when the liquid content is used up. The pump (6) is provided to the lid member (4) and configured to pump up the liquid content in the inner container (5) stored in the outer container (3) and to dispense the liquid content to an outside of the refillable container. When the opening (2) of the outer container (3) is closed by the lid member (4), a suction tube (15) of the pump (6), which is arranged below the lid member (4), is inserted from a suction port (8), which is formed in an upper surface (7) of the inner container (5), into the inner container (5).
