To provide a vehicle body wall structure for a railway vehicle capable of helping dispersion and reduction of peak stress and reducing the possibility of separating an FRP system from a panel.SOLUTION: A wall structure 10 for forming a wall of a railway vehicle body includes a metal panel 20 in which an opening 21 is formed and a fiber reinforced plastic reinforcing system 30 attached to the metal panel 20 at a corner 22 of the opening 21. The FRP reinforcing system 30 includes a laminate of FRP laminae arranged such that as the lamination proceeds from a base lamina 31, the area of each lamina in the laminate becomes smaller than the area of the previous lamina.SELECTED DRAWING: Figure 2
