PROBLEM TO BE SOLVED: To provide electrocoating equipment which can achieve a homogeneous electrocoating without influence of contamination caused by inadequate cleaning in a pretreatment process and is attached to an article to be coated. SOLUTION: The electrocoating equipment provided with an electrodeposition tank 2 for accommodating a liquid electrocoating 1, a transportation means 4 for putting the article 3 into the electrodeposition tank 2 and putting it out after electrocoating, and an electrifying means for depositing the electrocoating 1 on the surface of the article 3 by means of applying a direct current voltage between the article 3 and an electrode plate 17, so as to make the article 3 which is put into the electrodeposition tank 2 and dipped in the electrocoating 1, to be one anode, and so as to make the electrode plate 17 which is arranged in the electrodeposition tank 2 separately from the article to be coated 3, to be the other electrode, is characterized by an electrocoating discharging means 40 for discharging the electrocoating 1 towards the article 3 in the electrodeposition tank 2, while the article 3 is dipped in the electrocoating 1 after it has been put in the electrodeposition tank 2 and before an electrodeposition is substantially started.
