に対する耐久性が向上できる。The water- and oil-repellent coating is a reaction product containing a silane compound as a main component. Side chains having low surface energy such as methyl groups are oriented on the surface of the reaction product. As a result, the adhesive force with the dirt component decreases,
It has the effect of preventing dirt. The water- and oil-repellent coating is formed by dehydration-condensation of an alkoxy group, which is a functional group of a silane compound, and a silanol group appearing on the glass surface. This bond is a covalent and strong bond. However, when rubbed by a metal pot or a frying pan, the water- and oil-repellent coating easily peels off.
Therefore, in the present invention, as shown in FIG. 1, the glass surface is processed into irregularities of a specific roughness, and a water- and oil-repellent coating is formed inside the concave, thereby preventing the loss of the water- and oil-repellent performance due to friction. In. That is, on a smooth surface having no irregularities, the coating is uniformly worn with use, but on a rough irregular surface, a water-repellent and oil-repellent surface which is not rubbed by the concave portions as shown in FIG. 2 remains. However, if the concavities and convexities are made larger than necessary, the dirt component will be caught on the protrusions and remain. The maximum roughness was 0.4 μm as a result of evaluation using salad oil. Since the water- and oil-repellent coating of the present invention is mainly composed of a silane-based compound having a reactive group at only one end, it is considered that single molecules are arranged side by side as shown in FIG. The film thickness is about the length of a single molecule, 0.01μ
thinner than m. Therefore, if the concave portion on the surface is about 0.05 μm, a water- and oil-repellent coating can be formed in the concave portion. For the above reasons, the surface roughness of the glass is 0.05
When the thickness is not less than μm and not more than 0.4 μm, it is possible to prevent dirt from entering into the concave portion of the surface, and to improve durability against friction.

Here, the heating cooker is an electromagnetic cooker, a microwave oven, an oven, a gas table, a gas stove, or the like. When cooking is performed using a heating cooker, members such as a top plate, a saucer, and a grill are contaminated by generated oil vapor, oil smoke, spilled juice and the like. In particular, the degree of contamination is remarkable on the top plate, which is the top plate of the electromagnetic cooker. Here, the electromagnetic cooker is a cooking utensil that heats and cooks a metallic cooker by an electromagnetic induction method. FIG. 4 shows an electromagnetic cooker. The top plate on the top of the electromagnetic cooker is called a top plate and is made of a crystallized glass material that does not generate heat by itself. On the top plate, a pot or a frying pan is placed and cooked, so that various dirt sticks. By applying the water-repellent and oil-repellent glass to a member that is significantly contaminated as described above, the cooking device can be used cleanly for a long period of time.
