PROBLEM TO BE SOLVED: To provide an electrically conductive base material for plating for producing a conductor layer pattern-fitted base material useful for an electromagnetic wave shielding member subjected to patterning so as to have electrical conductivity and light transmissivity using a transferring process with high productivity. SOLUTION: The electrically conductive base material for plating has a projecting part pattern and recessed parts with the shape of geometric figure drawn thereby. An insulation layer is formed on the surface of each recessed part at a position lower than the position lower by 0.5 to 3μm from the upper end of each projecting part, the width of the exposed part of each projecting part in the electrically conductive base material is 1 to 40μm, and the height of each projecting part after the application of the insulation layer to each recessed part is≥10μm. It is preferable that, as the exposed part of each projecting part progresses to the tip direction, the width is not widen, and, as the whole, the width is reduced at the upper part compared with the lower part.
