The synthetic resin does not deteriorate even when used in an atmosphere containing water, for example. Since the monomolecular film is chemically bonded directly to the surface of the filler and is formed to have a uniform thickness and is extremely thin, the surfactant is not peeled off even if it is used for a long time and is highly reliable. Further, the characteristics of the filler are not impaired.
