A diaphragm-electrode system for electrocoating including an electrode provided as a counterpart electrode corresponding to a substrate that functions as an electrode on one side, and a diaphragm that serves to separate the counterpart electrode from the foregoing substrate acting as the electrode opposing to the former, as well as from the paint components in aqueous solution for electrodeposition. The diaphragm is disposed in a form to encircle the outer surface of a diaphragm backing member. The diaphragm backing member is tubular in form and made of insulating material having a water permeating structure. The counterpart electrode is encased inside of the diaphragm backing member. Between the counterpart electrode and the diaphragm backing member, a water running mechanism is provided in order to forcibly flow water from one side along a direction to the other side. The counterpart electrode placed within the diaphragm backing member is so inserted that it is freely installed or detached by operating from the outside.
