Abstract
A monitoring method of the invention is for monitoring electrodeposition coating of an object to be coated in which a conveying mechanism that conveys the object to be coated while the object is immersed in an electrodeposition paint in an electrodeposition bath, and a plurality of electrodes arranged along a conveying direction in which the object to be coated is conveyed by the conveying mechanism, are used, the method including: acquiring present position data of the object in the conveying direction; when the acquired present position data has a value corresponding to a predetermined determination position, acquiring an electric current value corresponding to a predetermined one, associated with the determination position, of the electrodes; and determining the occurrence of the abnormality for the object to be coated that is positioned at the determination position, based on whether the acquired electric current value is within a predetermined range.
