Abstract
An electrostatic powder coating method of forming an undercoating film having a volume specific resistivity of not more than 10.sup.13 .OMEGA..multidot.cm and a thickness of not more than 200 .mu.m on a metal surface and forming an overcoating layer on the undercoating film by electrostatic powder coating. The undercoating film is composed of a plurality of layers with only the top layer containing a conductive material.
