するという問題点があった。[Prior Art] Conventionally, in order to apply a sticky top coat to the cooking surfaces of hot plates, electric pots, frying pans, etc., the cooking surface of aluminum alloy die-cast molded products is roughened by sandblasting, etc. I applied an undercoat and topcoat of base resin paint and baked it. Alternatively, after roughening the surface, alumina-based ceramic was dispersed and deposited on the cooking surface using plasma spraying, and the cooking surface was finished with an undercoat and topcoat of fluororesin paint, and then baked. Surfaces finished using these methods have a smooth finish. That is, the surface of the uppermost layer is a smooth surface in which the unevenness of the base surface and the unevenness of the ceramic spraying are buried. However, a metal spatula could not be used on the surface of the uppermost coating film (finished with fluororesin paint) formed by such a finishing method for the following reasons. In other words, if you rub it with a metal spatula,
Because the contact area between the metal spatula and the film is large, and also because the fluororesin layer with a thickness of 20 to 60 μm softens at around 200°C, there is a problem that the surface to be adhered is scraped and peeled off. Ta.

A cooking surface structure including a non-adhesive layer 5 having a thickness of 10 to 30 μm and its rough surface X was used as the cooking surface of a hot plate shown in FIG. Since the side surface 13 of the inner surface 16 of the hot plate 15 is not a cooking surface, there is no opportunity to scrape it with a metal spatula. Therefore, on the side surface 13, the thickness B of the ceramic sprayed layer is 10 μm or more, and the thickness A of the fluorine coat is 10 μm or more.
The condition that the thickness be ~30 μm is not necessary. Side 13
The inner surface of the inner surface was formed such that the ceramic sprayed layer was dispersed and the fluororesin layer had a film thickness A of 20 to 40 μm, that is, the film was constructed so that it would be slightly scratched when rubbed with a metal spatula.
