PROBLEM TO BE SOLVED: To provide a manufacturing method that prevents damages caused by strength shortage of a working board, in the manufacture of a printed-wiring board that has thin board thickness and does not contain glass fiber. SOLUTION: This printed-wiring board is manufactured by a working board, where a reinforcing plate 3 in a shape where a printed-wiring board product part is eliminated, is held between two pieces of copper foil 2 with resin 1 for laminating. As the reinforcing plate, a prepreg containing glass fiber, a polyimide film, a stainless thin plate, or the like is used. The reinforcing plate will not remain in the printed-wiring board product with thin board thickness, after the shape is machined.
