PROBLEM TO BE SOLVED: To provide an electrodeposition coating apparatus for controlling the quantity of a coated film or the thickness of the coated film when actually coating an article to be coated, by a simple method. SOLUTION: The electrodeposition coating apparatus 1 is provided with an electrodeposition tank 11, a plurality of electrodes 12 and a voltage-applying circuit 13, and comprises: ampere meters 14A to 14L for measuring a chronological change of an electric current passing through each electrode or an electrode group consisting of a plurality of the electrodes in proximity to each other; an extraction circuit 15 for extracting the measured chronological change of the current passing through each electrode or each electrode group, by the ampere meters, on the basis of a chronological transportation history of the article which is an object to be measured; an arithmetic circuit 16 for determining a coulomb quantity having passed through the article of the object to be measured, by chronologically integrating the changes of the current having passed through each electrode or each electrode group extracted in the extraction circuit; and a voltage control circuit 17 for controlling a voltage applied to the electrode or the electrode group on the basis of the determined coulomb quantity.
