ABSTRACT OF THE DISCLOSURE A lid for a can-shaped container which lid is adapted to be connected to a peripheral wall of the can- shaped container is disclosed which comprises a can-shaped container lid base having a gas barrier-type multi-layer base, a thermoplastic resin layer, a score portion formed by thinning part of the thermoplastic resin layer on the upper surface of the bottom of the base into an annular shape; and a synthetic resin tab for opening the can- shaped container lid. The tab is connected to an upper surface of a tab seat constituted by that portion of the thermoplastic resin layer disposed inwardly of the score portion. The score portion is provided by forming a tunnel-like groove at the outer periphery of the tab seat in such a manner that the tunnel-like groove has a suitable height from the surface of contact between the tab seat and the bottom of the can-shaped container lid base, with the thermoplastic resin layer remaining on its outer side above the tunnel-like groove, so as to expose the upper bottom surface of the base to the base to the interior of the tunnel-like groove.
