Abstract: An optical electrical module includes a first substrate, a second substrate, a bearing portion and at least one optical electrical element. The second substrate is combined with the first substrate and has a reflective surface facing to the first substrate. The bearing portion is disposed between the first substrate and the second substrate to limit at least one light guide element. The optical electrical element is disposed on a surface of the first substrate facing to the reflective surface and faces to the reflective surface. The optical electrical element is configured for providing or receiving light signals. The reflective surface and the light guide element are disposed on an optical path of the light signals.
