Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pre-coating treatment method capable of preventing the occurrence of a chemical conversion defect by appropriately removing an oil-component carried into a chemical conversion treatment process before electrodeposition coating. SOLUTION: In the pre-coating treatment method of forming the chemical conversion coating on a surface of a body 4 by immersing the body 4 into a chemical conversion treatment liquid after a degreasing/cleaning process and prior to the electrodeposition coating process, the treatment is applied to the body 4 by immersing the body in the chemical conversion treatment liquid in the state of suspending an oil adsorptive resin block 17 in a chemical conversion treatment vessel 11 filled with the chemical conversion treatment liquid.
