PROBLEM TO BE SOLVED: To provide a structure of an inexpensive printed board and can realize highly reliable connection. SOLUTION: The central part on one end edge 3a of a main board 3 is designed as a fitting position of a board-to-board connector 10 to a line of soldered land 9 formed on the main board 3, and a cutting planned line 12 is formed inside the one end edge 3a in a manner to pass the board-to-board connector 10 to the lined soldered land 11 formed apart from the one end edge 3a than the soldered land 9. The cutting planned line 12 is formed by making a V-shaped groove on the same positions on both surfaces of the main board 3 and weakening the main board 3, so that it can be cut without using a special jig. Assuming a case when two kinds or more of products are to be manufactured in terms of fitting structure, a second cutting planned line for adjusting the board size may be formed at another position instead of the formation position of the cutting planned line 12.
