Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a deep cold air separating device to be high in energy efficiency and excellent in environment property by a method wherein liquefied nitrogen gas or liquefied oxygen gas is easily manufactured from a device by effectively utilizing a cold heat of liquefied natural gas or raw material air can be cooled and further through combination of the separating device with a CGS. SOLUTION: The low temperature air separating device manufactures at least one of vaporizing nitrogen gas and vaporizing oxygen gas as product gas from raw material air. By heat-exchanging at least a part of product gas with liquefied natural gas fed through an external feed pipe 17 from the outside of the device, product gas is cooled and liquefied.
