An aluminum-plated steel plate with a specific surface roughness range is used as the working metal base material. Aluminum-plated steel sheets that are commonly distributed are subjected to a so-called dull treatment, and the surface roughness is 5.0 μm in centerline surface roughness (r-). Considering the stain resistance of a high-frequency heating device with a heater, the type of paint is related to this stain resistance, but the surface roughness of the base material should be 1.5 zzm or less in terms of centerline surface roughness (RA). It has been found that particularly excellent stain resistance can be obtained.
