<p>PROBLEM TO BE SOLVED: To provide a manufacturing method for a flexible printed circuit board, in which damage generated in a cathode roller can be reduced and a continuous line for a one-sided board and a double-sided board can be easily shared thereby and an intermediate product.SOLUTION: The manufacturing method for a flexible printed circuit board P performs: a board forming step for providing thin protruding portions 44, thinner than other portions of a board 10, on the surfaces of which conductor layers 42 exist, and forming the board 10 so that the thin protruding portions 44 exist in succession to surfaces differing from each other between one end side and the other end side in a length direction of the board 10; a connecting step for connecting a conductor layer 42 of the thin protruding portion 44, which exists on the one end side of the board 10, to a conductor layer 42 of the thin protruding portion 44, which exists on the other end side of another board 10, so as to form connection portions; and a fastening step for fastening the connection portions by connecting members 60 that are arranged on one surface and the other surface respectively.</p> |
