- connection component includes an electrode to be electrically connected to the second substrate. Therefore, by connecting the connection component to the second substrate, the light transmission module and the second substrate can be electrically connected. Therefore, since it is not necessary to separately provide a member for electrically connecting the light transmission module and the second substrate, the space on the second substrate can be effectively used, and the second The entire module including the substrate and the optical transmission module can be miniaturized.
- the first substrate has a larger stagnation rigidity than the second substrate in the light transmission module described above.
- the first substrate since the first substrate has a higher stiffness than the second substrate, even when the second substrate is deformed by the influence of an external force or the like, the second substrate is Deformation of the substrate is less likely to occur. Therefore, since the positional relationship between the optical element and the optical waveguide can be kept constant, stable data transmission can be achieved without changing the optical coupling efficiency.
