PROBLEM TO BE SOLVED: To provide a splittable board which is shipped as a single board and can be divided on a user side into a plurality of sub-boards which have almost the same function at both before and after the division.SOLUTION: A board 1 has a complete function as a single piece. The board includes two or more sub-boards 2 (2a, and 2b) electrically connected to each other. These two or more sub-boards 2 can be divided. After the division, the sub-boards 2 are electrically connected to each other again, to provide a complete function that is equivalent to a single piece of the board 1. The two or more sub-boards 2 are obtained by cutting a division band such as a V cut groove provided on the board 1. The sub-boards 2 have respective connection terminals 4, and the connection terminals 4 are connected together again by electric connection means. A printed wiring may not be bridged over a border portion between adjoining sub-boards, and means for electrical conduction using soldering or conductive paste or the like may be used for easy division. |
