PROBLEM TO BE SOLVED: To provide an electrodeposition paint composition which has excellent heat resistance, superior insulating property and high safety and which can easily be produced. SOLUTION: A polycondensation polyimide resin, a thermally crosslinked imide resin and a hydrophilic cationic polymer are mixed, and thereto a lactic acid is added as an acid neutralizer and mixed for a predetermined time, thereby neutralizing the mixture. Into the mixture, purified water is supplied to thereby disperse these resins in water. A composition ratio formed between respective resins at this time is specified such that the polycondensation polyimide resin is 5 to 60 weight %, the thermally crosslinked imide resin is 10 to 80 weight % and the hydrophilic cationic polymer resin is 15 to 85 weight %.
