PROBLEM TO BE SOLVED: To improve unsealability when opening an upper lid plate without changing sealability and resealability. SOLUTION: A paper-made sealed container consists of a continuous arrangement of a box body (A) and a lid (B) assembled from a blank sheet obtained by punching a single sheet of cardboard. An upper lid plate (18) constituting the lid (B) is formed with a crease (g) for transforming the lid. The crease (g) can be formed by connecting both ends of the upper lid plate (18) via a line, connecting them via a line approximately symmetrically from the center of the border with a lid front face plate (181) toward both corners closer to a rear face plate (14) or by connecting one of corners closer to the rear face plate with one of corners closer to a front face plate via a line.
