Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of an ultralow temperature cold storage device using helium gas as a cold storage member and functioning with a compact and single body.SOLUTION: A manufacturing method of an ultralow temperature cold storage device includes the steps of: supplying helium gas into a helium gas encapsulation pipeline 64 of which both ends 64A, 64B are opened; closing the terminal part 64B of the helium gas encapsulation pipeline 64; filling the inside of the helium gas encapsulation pipeline 64 with helium gas from a gas supply device 75 in a state of cooling the helium gas encapsulation pipeline 64; and closing the starting end part 64A of the helium gas encapsulation pipeline 64 after filling the helium gas encapsulation pipeline 64 with helium gas.
