<p>PROBLEM TO BE SOLVED: To improve reliability for connection and to facilitate optical connection and electric connection when connecting one or plural second optical/electric wiring boards (daughter boards) with a first optical/electric board (mother board). SOLUTION: The first optical/electric wiring board has, on the surface thereof, a connector 5 for being fitted into the second optical/electric wiring board, and has an optical coupling part 41 below the connector 41 and an impinging part 6 inside the connector 41. The second optical/electric wiring board has, at the connecting end thereof, an optical coupling part and the impinging part 6 near the connector. The second optical/electric wiring board is fitted into the first optical/electric wiring board, and optical connection and electric connection are performed concurrently.</p> |
