<Problems to be Solved by the Invention> However, when the above printed wiring board is used, the plated lead wires protrude from the outer edges of the printed wiring board, so it is difficult to use the plated lead wires, especially at the outer edges of high-density printed wiring boards. It was confirmed that leakage occurred due to plated lead wires in humid conditions, causing abnormalities in the operation of electrical circuits.
