PROBLEM TO BE SOLVED: To provide a masking member which is used when stacked workpieces are electroplated in a lump to have a plated film formed thereon, makes the film formed so as to have more uniform thickness and quality, and makes the film formed in a shorter time; and also to provide a plating method. SOLUTION: The masking member 10 is liquid-tightly inserted between the adjacent workpieces (W), for the steps of stacking a plurality of the workpieces (W) having penetrating apertures so that the apertures can communicate with each other, and forming a plated film on the inner peripheral surface of the respective apertures in a lump with an electroplating method. The masking member 10 has a hole having approximately the same shape as the aperture, and notches 13 which are formed in each of both sides of a bottom edge 12 that determines the holes, and make room between both sides of the bottom edge and the workpiece.
