摘要:
The present invention provides a plating film 50 including a nickel plating layer containing phosphorus and a gold plating layer formed on the nickel plating layer, wherein the nickel plating layer has a phosphorus content of 11 to 16 mass %, and wherein (3×σ×100)/X is 10 or less, where X and σ are the average value and standard deviation of the phosphorus content in a surface of the nickel plating layer on the gold plating layer side, respectively; and a module substrate 100 having the plating film 50.
