The UV paint 7 containing a sensitizing agent is applied to the lower surface of the building board body 1, and the coated surface is irradiated with ultraviolet rays to harden the UV paint 7.It is made of synthetic resin that does not easily generate static electricity. The lower surface of the building board main body 1 is coated with seven layers of UV paint that is less likely to generate static electricity, so that the lower surface side is less likely to generate static electricity and can prevent contamination due to adhesion of dust.

A water repellent layer 3 such as silicone resin is applied over almost the entire surface of the board, and a back sheet 8 is applied to the open end of the building board body 1 and the outer surface of the foamed resin 2, which is the road surface. The paint-impregnated paper 4 side is adhered over almost the entire surface with a urethane adhesive 9 to form the building board A.
