In order to perform surface treatment such as electroless plating in a high quality on the work which is held vertically, each tank such as an electrolytic copper plating tank (200) includes a liquid squirting part (4) having a squirt port (6). The processing solution (Q) is squirted from the squirt port (6) toward a plate-shaped work (10) obliquely upward to a horizontal plane, and the processing solution (Q) is applied to an upper part of the plate-shaped work (10) held by a hanger (16) for return so that the surface of the plate-shaped work (10) is coated with the processing solution (Q) while the processing solution (Q) runs down the plate-shaped work (10). |
