Beschreibung
Zusammenfassung:	The present invention provides a metal can having a cap (20) that is fixedly fastened to the periphery of a bead part (14) and is opened by breaking up a score by pulling a tab, in which the bead part (14) is formed by curing outward the opening peripheral edge at the end of a mouth (13) that continues to a body and is tilted inward, wherein the start position for tilting is arranged between the lower end of the bead part and the start position for beading. Since the bead part (14) is tilted inward, the cap can provide sufficient airtightness even if a small-diameter sealing cap of a common structure is used, where, in the common structure, the airtightness is secured at a portion closer to some extent to the center of the cap.
