This is considered to improve the performance. Although the reason is not clear, it can be considered as follows.
- tin ions when tin ions are present, it is considered as follows. Tin ions are less susceptible to steel plate effects than zirconium ions, so it is easy to form an oxide film on the substrate. Although tin ions do not specifically form a film on a portion where zirconium ions are difficult to precipitate, tin ions do not form an oxide film on a specific portion. As a result, the tin ion forms a film by compensating for the part where the zirconium ion could not be formed.
- the metal surface treatment liquid for cationic electrodeposition coating of the present invention can improve the adhesion to the cationic electrodeposition coating film by containing a polyamine compound, and as a result, the conditions are more severe.

Moreover, the metal surface treatment liquid for cationic electrodeposition coating of the present invention can improve corrosion resistance by containing copper ions. The reason is not clear, but it is thought that some interaction is acting between copper and zirconium during film formation. Furthermore, when the metal surface treatment liquid for cationic electrodeposition coating of the present invention contains a large amount of metal other than zirconium, a zirconium oxide film can be stably formed by including a chelate compound. This is presumably because the chelate compound captures metal ions that are more likely to precipitate than zirconium.
