When the joints are formed with mortar, it is time-consuming and takes time to form the wall surface portion 11. According to this embodiment, the wall surface portion 11 can be formed as follows. The exterior panels 20 are attached to the wall body 10 so as to be lined up in a vertical row. The joint members 30 are arranged along the exterior panels 20 lined up in a vertical row. Furthermore, the exterior panels 20 are attached along the joint members 30 so as to be lined up in a vertical row. In this manner, the joints can be easily formed between the two rows of exterior panels 20. The joint members 30 cover the mutually opposing lateral edges 25 of the two rows of exterior panels 20. The joint members 30 are members formed in advance at a factory and have a predetermined dimensional accuracy. Both edges of the cover portion 35 of the joint members 30 are close to straight lines. Therefore, the joints of this embodiment have less variation in the width dimension of the joints and have a better appearance than joints made with mortar.

The effects of this embodiment will be described.
(1) The wall 1 comprises a wall main body 10, a plurality of exterior panels 20 attached to the wall main body 10 with an adhesive 18, and joint members 30 forming joints of the wall 1. The plurality of exterior panels 20 are aligned in the vertical direction DV so that their horizontal edges 25 are aligned. The joint members 30 are disposed between two adjacent rows of exterior panels 20. The joint members 30 cover the mutually opposing horizontal edges 25 of the two rows of exterior panels 20.

According to this configuration, the exterior panels 20 are attached to the wall body 10 with adhesive 18. The joint members 30 are disposed between two adjacent rows of exterior panels 20. In this way, in the wall 1 configured as described above, there is no need to fit the exterior panels 20 between the two joint members 30, and the work efficiency of building the wall 1 can be improved compared to a wall structure that requires the work of fitting the exterior panels 20 into the joint members 30.

The cover portion 35 is configured so that the angle A3 when the cover portion 35 and the first fixing portion 33a intersect is equal to the angle A4 when the cover portion 35 and the second fixing portion 33b intersect.

With this configuration, when the second joint member 32 is attached to the inside corner portion 7 of the wall body 10, the cover portion 35 of the joint member 30 can be positioned so that the angle A3 with respect to the first surface 15a of the inside corner portion 7 and the angle A4 with respect to the second surface 15b are equal. This structure can improve the appearance of the wall 1.

(5) The outer surface 35a of the cover portion 35 has the same pattern as the outer surface pattern of the exterior panel 20, or has the same color scheme as the outer surface 20a of the exterior panel 20. This configuration allows continuity to be provided between the outer surface pattern of the exterior panel 20 and the joint member 30. This allows the exterior of the wall 1 to have a unified design.

(6) The outer surface 35a of the cover portion 35 is located closer to the wall body 10 than the outer surface 20a of the exterior panel 20. This configuration makes the joint member 30 less noticeable. This structure improves the appearance of the wall 1.
