This multi-layer wiring board (20) is provided with an insulating substrate (40), an inner layer copper sheet (50, 60), and an outer layer copper foil (70, 80). The inner layer copper sheet (50, 60) is disposed within the insulating substrate (40) and has been patterned. The outer layer copper foil (70, 80) is disposed in a state of having been patterned at the surface of the insulating substrate (40), is thinner than the inner layer copper sheet (50, 60), and has a cross-sectional area of the current path that is smaller than the cross-sectional area of the current path of the inner layer copper sheet (50, 60). As a result, provided are: a multi-layer wiring board that can flow a large current and a smaller current while suppressing an increase in the projected area of the substrate; and a method for producing the multi-layer wiring board.
