Since it is completely covered with f-film, it has a high heat resistance when used in, for example, a bath tub, and can be completely wiped off with a cloth or the like even if it gets dirty such as hot water. At this time, it is not necessary to use a so-called detergent or the like, so this advantage is great in that it reduces the pollution of sewage and the pollution of rivers and seas. Further, in a bathtub equipped with an automatic cleaning device these days, it is very convenient because if the surface is cleaned while the hot water is stored, the surface will be cleaned automatically. (If a detergent is used, it cannot be removed by the cleaning device.
