Claims

[Scope of utility model registration request]

A method for manufacturing a hollow panel by forming a hole, which is a hollow part, in a panel material plate, inserting or sealing a filler into the hole, stretching at least in the length direction of the hole, and then removing the filler. The hollow tube is characterized by being composed of a hollow tubular body and a content that is enclosed in the hollow part of the hollow tubular body and is made of a metal or alloy having a melting point lower than that of the hollow tubular body and the panel material plate. A filler in the panel stretching process.
