An easy-to-open metal having a pair of opposing score lines formed along a top plate, a tab for opening the package by tearing the score lines, and a layer of liner provided over the entire inner surface of the top plate. An easy-to-tear annular score portion is formed in the vicinity of the tab-side seal portion of the one-layer liner portion of the cap that corresponds to the area sandwiched between the opposing score lines, and a strong annular score portion is formed inside the score portion. An area where an adhesive is formed and which extends from at least the tab-side sealing part to the approximate center of the metal cap on the outside of the score part of the liner single-layer portion is such that the liner single-layer adheres to the top plate when unsealing. It is a weak adhesive area or a non-adhesive area that can be easily separated,
When opening the package by pulling up the tab and tearing the score line,
An easy-to-open metal cap characterized in that the score portion is torn to open a region within the score portion of the liner layer.
