The apparatus for electrolytically treating printed circuit boards,, through which apparatus the printed circuit boards are continuously guidable in a plane of conveyance in a substantially horizontal direction of conveyance, has the following features: Counter-electrodes,are disposed opposite the plane of conveyance and substantially parallel thereto on at least one side, so that electrolytic chambers,are formed between counter-electrodes, which are situated opposite one another, or between the counter-electrodes and the plane of conveyance, the counter-electrodes forming respective substantially continuous electrode faces. Guide elements,for the printed circuit boards are disposed in the electrolytic chamber. Contact elements,are provided for the electrical contacting of the printed circuit boards. Electrolyte spraying arrangements,are also provided for conveying the electrolytic fluid towards the surfaces of the printed circuit boards. Openings are provided in the counter-electrodes. The electrolyte spraying arrangements are disposed on the sides of the counter-electrodes remote from the plane of conveyance in such a manner that electrolytic fluid, emerging from the arrangements, can pass the counter-electrodes substantially unhindered at the locations of the openings and can pass to the surfaces of the printed circuit boards.
