PROBLEM TO BE SOLVED: To provide a method for manufacturing two printed board different in the outward form by using only one kind of master board. SOLUTION: In this printed board, slits 36, 37, 38, 39 for division into individual boards 11, 12 are formed in a master board 10. The printed board is turned into the individual boards having basic boards 15, 16 and extension boards 13A, 13B, 14A, 14B, by a process forming first cutting trenches 32, 33 at positions isolated from the slits of the master board, and a process dividing the master board by the first trenches. The printed board is turned into the individual boards having the basic boards 15, 16 by a process forming second cutting trenches at positions adjacent to the slits of the master board, and a process dividing the master board by the second cutting trenches. |
