Abstract
A method of plating treatment for forming a plated coating on the surface of a workpiece except on a region thereof comprises the steps of placing a masking member made of water swelling rubber in abutment against or in close proximity to the region of the workpiece where no plating is desired, immersing, in this state, the masking member in water to cause the water swelling rubber to undergo volumetric self-swelling, and immersing the workpiece in a plating solution with the swelled masking member pressed against the particular region of the workpiece.
