There is provided a gas separating device which is capable of being made compact and light. A part of an airtight container (2) is constructed by a gas separating membrane (13), and a gas separating membrane (13) is constructed to be able to separate and discharge at least a part of a gas g1 included in a gas G to the outside of the airtight container (2) from the gas G. A gas outlet valve is constructed to allow the inside of the airtight container and the outside to communicate with each other to be able to discharge a gas g2 remaining in the inside of the airtight container (2) to the outside when the total pressure of the inside of the airtight container (2) becomes P2 (P2>P1).
