Abstract
In a process which is before a treatment process of forming a chemical conversion, TiOfine particles as an electron releasing-related substance (electron releasing substance) are attached onto a surface of a vehicle body. Then, a chemical conversion treatment is applied to the vehicle body having the TiOfine particles attached thereto. Thereby, an energy band gap of a finally-formed chemical conversion film can be smaller than that of a chemical conversion film formed by using only a chemical conversion treatment agent. Accordingly, the number of electrons (free electrons) which can be supplied onto the surface of a chemical conversion film can be increased during a voltage application in an electrodeposition coating process, and reducing reaction at a cathode can be promoted.
