PROBLEM TO BE SOLVED: To make it possible to stably and firmly mount and fix external facing panels to a wall substrate for a long period of time while using bearing devices having usual strength in the case a plurality of external facing panels are arranged in both right and left directions to mount them to the wall substrate by making vertical siding so that the ends on both right and left long sides are arranged along the vertical direction. SOLUTION: While a female tongue section 9 having a female tongue interlocking groove 10 is formed in the left end of both ends on both right and left long sides of external facing panels 8, a male tongue section 13 is formed in the right end. The lower ends of the external facing panels 8 are borne on bearing devices 22 and 27 fixed to a wall substrate 5, a joint section between the female tongue section 9 and male tongue section 13 of the external facing panels 8 and 8 adjacent to each other in both right and left directions is so provided that it covers a female tongue interlocking piece 34 interlocking with the female tongue interlocking groove 10 of the female tongue section 9 and the male tongue section 13, and the external facing panels are mounted to the wall substrate 5 with a fixture 31 having a male tongue interlocking piece 35 fixed to the wall substrate 5 together with the male tongue section 13 by means of a nail 46 passing through the male tongue section 13 to fix.
