However, if the top of the fluororesin coat is colored, impurities such as a coloring agent are contained, so that not only the non-adhesive property is deteriorated but also the corrosion resistance is deteriorated. In particular, a pot heated by an alternating magnetic field caused by electromagnetic induction is exposed to a cladding material having a different potential between the aluminum alloy and stainless steel, which is exposed to the surface. There was a problem that the presence was unavoidable and the corrosion resistance was further deteriorated.

The appearance can be erased, and the hue that is superior to the design can be freely colored. Next, the top fluororesin coat is colored within a range that suppresses the occurrence of pinholes to improve corrosion resistance on the surface or within the range that suppresses browning due to deterioration of surfactants etc. during firing of the fluororesin coat, Impurities other than fluororesin, such as colorants, are reduced as much as possible, and pinholes are reduced to prevent non-adhesive deterioration. This prevents corrosion of the aluminum alloy due to infiltration.
