PURPOSE:To connect the intermediate part of a flexible printed board to other board by providing a land on a conductor, and forming a hole having a zigzag periphery through the land and a base film. CONSTITUTION:A land 12 is provided on the way of a conductor 11 of a flexible printed board 10, a hole 14 having a zigzag periphery is provided together with a base film 13 at the land 12, and a protective film 15 of the upper part of the land 12 is removed. In the case of the board having conductors on both side surfaces of the base film, it is necessary to remove a conductor part of the lower surface opposed to the land provided at the conductor of the upper surface. Thus, the intermediate of the board can be connected to other printed board. For example, the board 10 can be connected at the intermediate to other printed board 16, and since the hole 14 has the zigzag periphery, the connecting side with solder is lengthened to improve reliability of soldering.
