PROBLEM TO BE SOLVED: To suppress a surface material such as wallpaper from having a cut or slit at a squinch part of a wall body at a periphery of an opening part in a case of a shake of a building due to an earthquake etc., when the wall body is provided with the opening part.SOLUTION: A partition wall 10 has a first wall panel 11a and a second wall panel 11b, which is provided with a gateway 31. The second wall panel 11b has a substrate frame 21, and an upper surface material 22a and a side surface material 22b fitted to the substrate frame 21. The substrate frame 21 has a pair of substrate longitudinal materials 25, a substrate lateral material 26 connecting the pair of substrate longitudinal materials 25, an auxiliary longitudinal material 41 provided more on the side of the gateway 31 than the substrate longitudinal materials 25, and an auxiliary lateral material 42 provided more on the side of the gateway 31 than the substrate lateral material 26. The upper surface material 22a is fitted to the auxiliary longitudinal material 41 and auxiliary lateral material 42 across the border between the auxiliary longitudinal material 41 and auxiliary lateral material 42. |
