An integrated optical transmission board in accordance with one embodiment of the invention includes: a first optical transmission board having a first optical transmission line; a second optical transmission board having a second optical transmission line; and an optical coupling structure which is disposed between the first optical transmission board and the second optical transmission board and has a third optical transmission line for providing optical connection between the first optical transmission line and the second optical transmission line. The first optical transmission board further has a first engagement portion provided in an area thereof opposed to the optical coupling structure. The optical coupling structure further has a second engagement portion provided in an area thereof opposed to the first optical transmission board so as to make engagement with the first engagement portion.

Integrated optical transmission board and optical module

In a mounting structure of an optical module, an optical semiconductor device such as a light emitting device or a photo sensing device and an optical fiber are mounted. The optical fiber is directly mounted in a mounting groove formed on a top face of the substrate. The optical semiconductor device is mounted on a front face of a carrier corresponding to &lcub; &rcub; surface or &lcub; &rcub; surface equivalent to ( ) surface or ( ) surface of a single crystalline silicon. The carrier has a slanted first positioning face corresponding to &lcub; &rcub; surface equivalent to ( ) surface of the single crystalline silicon. The substrate has a slanted second positioning face corresponding to &lcub; &rcub; surface equivalent to ( ) surface of the single crystalline silicon with respect to the top face corresponding to &lcub; &rcub; surface or &lcub; &rcub; surface of the single crystalline silicon. Thus, the front face of the carrier becomes perpendicular to the top face of the substrate.
