PROBLEM TO BE SOLVED: To provide a building board for external facing, which can suppress a heat island phenomenon by facilitating release of heat absorbed from sunlight and the like, and which can hardly cause a rise in temperature on an indoor side, and an external wall structure.SOLUTION: A building board A for external facing is formed by being predominantly composed of a hydraulic inorganic material, and a back surface is coated with heat radiating paint. Additionally, an external wall structure includes the building board A for the external facing, a building frame 3, and a heat insulating sheet 2. The heat insulating sheet 2 is provided on the outer surface side of the building frame 3, and the building board A for an external wall is provided on the outer surface side of the heat insulating sheet 2. |
