A building board includes a base material, an insulating coating film for covering a surface of the base material, and a transparent clear coating film for covering the insulating coating film. The insulating coating film contains a coating film forming material, organic hollow particles, and a water-soluble solvent. The method for producing the building board includes a step of forming an insulating coating film in which an insulating paint is applied to a surface of the base material and then dried to form the insulating coating film, and a step of forming a clear coating film in which a clear paint is applied to a surface of the insulating coating film and then dried to form the clear coating film. The insulating paint contains a coating film forming material, organic hollow particles, and a water-soluble solvent. |
