It is conveyed on the belt conveyor 3 while being inclined. The predetermined angle is, for example, about 45 to 60 degrees with respect to the traveling plane, and is set so that each worker in each process can easily perform the corresponding work. The surface of the wiring board 1 that faces the worker is flat, and other than this surface, the wiring board 1 has a triangular prism shape constituted by a frame.

As described above, the surface of the wiring board 1 on which the exterior inspection drawing and the attention point drawing are attached is flat.
Since the surface other than this surface has the shape of a triangular prism formed of a frame, the weight of the wiring board 1 is reduced, and the wiring board 1 can run on the belt conveyor 3 stably.
