Abstract
An electrodeposition coating method includes a degreasing/cleaning step, a chemical conversion step, and an electrodeposition coating layer formation step. The degreasing/cleaning step includes a degreasing step of ultrasonically vibrating a degreasing solution in which a target object is immersed, using an ultrasonic vibrator. The electrodeposition coating layer formation step includes: a first electrodeposition step; a first rinsing step; a rinse water removal/reduction step of removing or reducing rinse water on a rinse water stagnating surface of the target object; a thermal flow step of allowing the first electrodeposition coating film to thermally flow so that the first electrodeposition coating film formed on a portion of the target object near a first counter electrode has a higher electrical resistance than the first electrodeposition coating film formed on a portion of the target object far from the first counter electrode; and a second electrodeposition step.
