Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of manufacturing a metal bellows formed nearly even in plate thickness and shape of crest parts and valley parts of a bellow part and having a low spring constant. SOLUTION: The metal bellows 1 is manufactured through a first process for obtaining a primary molding 1b by bulging so as to form a waved bellows part 11 on the peripheral surface of a straight raw pipe 1a, and a second process for rolling at least the valley parts 11b of the bellows part of the primary molding by a pair of forming rollers 31 and 32.
