  Conventionally, the wiring of solar panels arranged on a sloped roof is generally drawn indoors from the outer wall that forms a vertical surface or the back of an eave that forms a horizontal surface, and therefore the piping used for the wiring is exposed outdoors. . Such exposed piping has a problem of affecting the exterior design of the building. In order to avoid this, for example, as shown in FIG. 14 and FIG. 15, there is a case where a wiring processing method called concealed wiring in which wiring is drawn into the indoor side from the roof slope surface directly below the main body of the solar panel 30 is used (for example, Patent Document 1).

  In this concealed wiring, a wiring lead-in metal fitting 31 is generally used. The main body of the wiring lead-in metal fitting 31 is on the outdoor side through a roof material 32, a waterproof layer 33 such as asphalt roofing, and a roof base material 34 such as a field board. And fix with screws 35. When the wiring cable 36 is retracted, a through hole 37 is opened from the outdoor side in the roof material 32, the waterproof layer 33, and the roof base material 34, and the wiring lead-in fitting 31 is disposed in the through-hole 37. The wiring cable 36 is drawn into the indoor side from the inlet.
