PROBLEM TO BE SOLVED: To provide a printed circuit board of novel structure which allows for easy manufacturing of a printed circuit board having a wiring pattern of different specification by using one kind of printed circuit board, without requiring any separate member such as a jumper wire.SOLUTION: In a printed wiring board 10 provided with a plurality of printed wirings 16, 20, adjoining printed wirings 16, 20 are connected by a bridge wiring 22, and auxiliary holes 24 for bridge cut are around the bridge wiring 22, so that the circuitry can be changed by forming a penetration part 28, penetrating the auxiliary holes 24 for bridge cut and the bridge wiring 22, and cutting the bridge wiring 22.SELECTED DRAWING: Figure 2 |
