Provided is a vehicle interior board that is equipped with a foldable hinge section, has a small number of components and excellent productivity, and is lightweight and very strong. This vehicle interior board is equipped with: first and second boards (10, 20) that are constructed by forming hard foamed polyurethane layers (13, 23) in spaces that are respectively sandwiched by pairs of thin plates (11, 12, 21, 22); and a connecting member (30) that comprises a porous structure having a recessed groove (34) and is partially placed inside the spaces. The hard foamed polyurethane layers (13, 23) are also formed in gaps (18, 19, 28, 29) between the thin plates (11, 12, 21, 22) and the connecting member (30) so as to connect the respective boards (10, 20) and the connecting member (30) together. Consequently, the respective boards (10, 20) can be formed and connected together into one body during the formation process of the first board (10) in order to form a foldable, lightweight, and very strong vehicle interior board (1). As a result, the number of components can be reduced, the manufacturing process can be simplified, and the productivity can be improved. |
