1. An optical transmission module comprising:
a first substrate having a surface;
a driving circuit disposed over the surface of the first substrate;
one or more wirings disposed in contact with the first substrate;
an optical element having a first surface and a second surface and including a light emitting element, the second surface of the optical element disposed over the one or more wirings along a plane that is transverse to the second surface of the optical element, and the optical element is electrically connected to the driving circuit via the one or more wirings;
