PANEL MANUFACTURING METHOD

The present invention provides a method for manufacturing a panel by which the formation of a blister-shaped inflation portion at the boundary between an intermediate portion and a hinge can be suppressed, even when the size of the intermediate portion is small. According to the present invention, provided is a method for manufacturing a panel, wherein the panel comprises first and second main body portions, and a hinge portion, the hinge portion comprises first and second hinges extending in parallel and an intermediate portion arranged therebetween, the first main body portion and the intermediate portion are connected by the first hinge so as to be able to pivot relative to each other, the second main body portion and the intermediate portion are connected by the second hinge so as to be able to pivot relative to each other.
