PROBLEM TO BE SOLVED: To prevent release of a laminated panel due to the internal residual air of the laminated panel, by securing an air byway during bonding of the panels, with regard to a structure for preventing the laminated panel which is obtained by bonding and stacking a plurality of panels from being released. SOLUTION: In the laminated panel 1 formed of a skin material 3 joined to a base material 2 by a contact-bonding process through an adhesive, a first groove part 8 with a specified width and a specified depth, is formed, at a specified interval, on the surface of the base material 2, to which an adhesive is applied. In addition, second groove parts 9 are formed in such a way that their width and depth are larger than those of the first groove part 8 and besides, at a wider interval than that of the first groove part 8 in the short side direction of the surface of the base material 2. |
