PROBLEM TO BE SOLVED: To provide an optical wiring board having highly fine optical wiring on a supporting board in which the reference surface of a portion for installing an optical wiring layer and the reference surface of a portion for installing a photodetector and/or a light emitting device have different heights on the supporting board, and also having improved latitude of design on which a 90°optical path conversion structure can be formed in an arbitrary portion. SOLUTION: The optical wiring board is provided with the optical wiring layer, the photodetector and/or the light emitting device on the supporting board in which the height of the board in a portion for installing the optical wiring layer and that for installing the photodetector and/or the light emitting device are different. The optical wiring layer comprises at least an optical wiring film and an adhesive layer. Moreover, the portion for installing the optical wiring layer on the supporting board has a shape capable accepting insertion of the optical wiring film. The portion for installing the photodetector and/or the light emitting device on the supporting board has a shape capable of accepting insertion of the above devices. COPYRIGHT: (C)2004,JPO |
