| 摘要 |
The purpose of the present invention is to make an inter-circuit board optical interconnection that allows circuit boards for transmitting and receiving an optical signal to be easily positioned relative to each other without requiring time and cost for forming each of the circuit boards. In a plurality of circuit boards (10) of an optical interconnection device (1), a light emitting element (11) and a light receiving element (12) on each of the circuit boards (10) have a common arrangement pattern. In two circuit boards (10) for transmitting and receiving an optical signal, the direction of the arrangement pattern of one circuit board (10) rotates at a set angle with respect to the direction of the arrangement pattern of the other circuit board (10), and the light receiving element (12) on the other circuit board (10) is disposed on the optical axis of the light emitting element (11) provided on the one circuit board (10). |
