Hereinafter, the operation of the present invention will be described. By using the means according to the present invention, it is possible to produce a honeycomb-shaped panel which is free from harmful undercut defects and excellent in welding strength and appearance. This is because by making the vertical wall of the honeycomb core as perpendicular as possible, there is no gap between the face plate and the honeycomb core, and the occurrence of harmful undercut defects is suppressed. If the angle of the vertical wall of the honeycomb core is 80 degrees or less, about 30% or more of the thickness of the face plate is dented, and the welding strength is insufficient, which causes peeling. Also, 9
If the angle is 0 degrees or more, the strength of the honeycomb panel becomes insufficient.
