PROBLEM TO BE SOLVED: To appropriately peel a decorative sheet from a game board. SOLUTION: This game board 1 is configured to connect the decorative sheet 3 to the game board 2 made of plywood such as veneer with acrylic adhesive material 4, and the decorative sheet 3 is configured to print a decorative layer 6 on the back face of a surface panel composed of a transparent polyolefine synthetic resin. When the game board 1 is heat treated 7 for removing the decorative sheet 3 from the game board 1, an adhesive force of the acrylic adhesive 4 to the game board 2 is lowered, a corner part of the surface panel 5 consisting of polyolefine synthetic resin is warped in the direction of separating from the game board, and the corner part of the decorative sheet 3 and the corner part of the acrylic adhesive material 4 are separated from the game board 2 together, so that the corner part of the decorative sheet 3 and the corner part of the acrylic adhesive material 4 separate from the game board 2 are manually or mechanically pulled relative to the game board 2 in the direction shown by an arrow X1 and the decorative sheet 3 and the acrylic adhesive material 4 are appropriately peeled from the game board 2.
