PROBLEM TO BE SOLVED: To provide a deaeration bag which can maintain airtightness as much as possible and be easily handled, a suction nozzle, and the combination thereof. SOLUTION: The air in the deaeration bag is sucked by a suction nozzle connected to a suction pipe or a suction hose of a vacuum cleaner. A small deaeration bag 10A is provided in the deaeration bag in order to insert the nozzle therein. The small bag 10A comprises two resin films 11 and 12, and openable/closable by a fastener 15 formed of uneven parts. The suction nozzle comprises a substantially cylindrical body having a connection part which can be connected to the vacuum cleaner on a rear part thereof, a non-return valve element, and a suction port on a front end part. The rear part for connection is bent upwardly, the front end part is spatula-shaped, and a suction port opened downwardly is formed. The outer circumferential dimension of the front end part having the suction inlet is substantially same as the inner circumferential dimension of an insertion part of the small deaeration bag 10A.
