The present invention provides a building material in which a coating is applied to a front surface and a side surface is sufficiently adhered to a sealing and method for manufacturing thereof. In a building material in which a coating is applied to a front surface, a coating film on a side surface is removed or reduced by laser irradiation. The part of the side surface in which the coating film has been removed or reduced by laser irradiation has a width of at least 5 mm from a front surface side toward a rear surface side of the building material, or extends over the entire side surface from the front surface side toward the rear surface side of the building material, or is formed more than a part in which coating film is formed.
