PROBLEM TO BE SOLVED: To provide a waterproof structure in a wall panel joining part for properly and sufficiently coping even with a joining part with a wall panel for arranging an external facing material in advance. SOLUTION: This waterproof structure in the joining part of the mutual wall panels 1 with external facing material is formed by installing a waterproof sheet 12 and an external facing material 14 in advance on the surface of the rectangular wall panel 11 from above the waterproof sheet 12. The waterproof sheet 12 is installed on the wall panel 11 so that a side end part extends from a side end part of the wall panel 11. The external facing material 14 is installed on the wall panel 11 so that the side end part is positioned in the side end part of the wall panel 11. The reverses of the both waterproof sheets 12 are mutually adhered and folded back with a double-sided adhesive waterproof tape, and are formed as a folding-back part. This folding-back part is sandwiched between the wall panel 11 and a joint material installed in a joint formed between both external facing materials 14. COPYRIGHT: (C)2004,JPO
