It is an object to provide a flame treatment device capable of flame treatment without preheating a metal base material, a production device for a coated metal plate, and a method for producing a painted metal plate. In order to solve the above problem, the flame treatment apparatus includes a first temperature measuring unit that measures a temperature before flame treatment of a metallic substrate, and based on the temperature before flame treatment measured by the first temperature measuring unit, And a control unit for determining the combustion energy of the flame so that the surface temperature of the metal base material is 56°C or higher, and a flame treatment unit for performing flame treatment on the metal base based on the combustion energy determined by the control unit. |
