利用されることになる。[Prior Art] For example, as disclosed in Japanese Patent Publication No. 48-860, a core having a battledore-shaped cross section and a slit-shaped groove at the front end is placed in a mold, and the mold By extruding the molten synthetic resin through the space above and below the core and the slit-like space on the front end side of the core, it becomes possible to obtain a hollow panel-shaped molded body with a harmonica-shaped cross section. Such molded bodies are not only strong, but also light in weight because they are hollow, and have heat insulating properties because they contain air, and are used as building materials. In particular, such hollow panels will be used as interior materials for walls and the like.
