PROBLEM TO BE SOLVED: To allow to take pleasure in separating a sealing part and pasting it to a desired article by rebondably providing the separable sealing part at least one surface side of a book cover bound on the cover paper of a book. SOLUTION: A book cover 1 has a base material 2, an ink layer 3 on the rear surface side of the book cover, an ink layer 4 on the front surface side of the book cover, a self-adhesive layer 5, a transparent film layer 6, a silicone layer and a sealing part 8. The self-adhesive layer 5 is to separate the sealing part 8. The transparent film layer 6 is made of a transparent resin so as to allow to see the ink layer 4 through the transparent film layer 6 and the self-adhesive layer 5. In one portion between the transparent film layer 6 and the self-adhesive layer 5, a transparent silicone layer 7 is formed. Its outline shape is nearly the same shape and size of that of the sealing part 8. The part of the base material corresponding to the silicone layer 7 is made to be sealing part 8, in the outline part of which a cut 9 is formed.
