PROBLEM TO BE SOLVED: To solve the problem that, although a plating solution in a treatment tank is stirred to improve the efficiency of the plating treatment and/or the finish in a plating treatment, typical stirring means, an air bubbling method, comprises stirring the plating solution by jetting air from a tube provided in the bottom surface of the plating tank and cannot achieve sufficient stirring of the plating solution, resulting in poor plating fixation, falling of work into the treatment tank and/or variation of the plating condition of the work.SOLUTION: An apparatus for treating the surface of work includes a treatment tank and a treatment solution poured in a treatment tank for forming a film on the surface of work put in the treatment tank. There are provided with take-out means of taking out the treatment solution poured in the treatment tank and a micro-bubble generating body which generates micro-bubbles by using the treatment solution taken out by the take-out means and a gas supplied separately. The treatment solution is stirred with the micro-bubbles generated by the micro-bubble generating body and forming a film on the surface of the work. |
