<p>A building board includes an inorganic board having a surface covered by an insulating coating film containing a coating film forming material and 5 organic hollow particles, wherein the organic hollow particles have an average particle size in the range of 5 to 50 pm and an average hollow ratio of 80% or more, and the insulating coating film contains 0.01 to 5.0 parts by mass of the organic hollow particles per 100 parts by mass of solid content thereof, and has an average thickness of 5 to 500 pm. The method for producing a 10 building board includes: applying, onto a surface of an inorganic board, an insulating coating material containing a coating film forming material and organic hollow particles; and drying the insulating coating material to form an insulating coating film.</p> |
