PROBLEM TO BE SOLVED: To provide an easily handleable and inexpensive composite wiring board. SOLUTION: After first and second substrate element pieces 2A and 2B are formed by laminating single-layered or laminated rigid wiring boards 20 and 30 and flexible wiring boards 10 upon another so that joints 42 composed of one end sections of the flexible wiring boards 10 may be protruded from one side faces of the pieces 2A and 2B, this composite wiring board is constituted by connecting the joints 42 of the pieces 2A and 2B to each other. Since the first and second substrate element pieces 2A and 2B can be handled individually until the joints 42 are connected to each other, the workability is improved. COPYRIGHT: (C)2004,JPO&NCIPI |
