Opto-electric hybrid module

An opto-electric hybrid module comprising:

• an optical element unit including an optical element;
• an opto-electric hybrid unit including an electric circuit board having electrical interconnect lines and an optical waveguide which are stacked together;
• and
• a board,
• wherein the optical element unit and the opto-electric hybrid unit are coupled together so as to be capable of light propagation,
• wherein the optical element unit is electrically connected with the board,
• wherein the optical element unit includes a connector body including an insertion recess for receiving one end portion of the opto-electric hybrid unit, the optical element mounted on the insertion recess, an electrical interconnect line embedded in a bottom, a ceiling and a side wall of the insertion recess, and an aligning protrusion in the insertion recess positioned and formed in a predetermined position with respect to the optical element,
• wherein the opto-electric hybrid unit includes a recess positioned and formed in a predetermined position on an outer peripheral side surface thereof with respect to an end surface of a core for an optical path of the optical waveguide,
• wherein, on an upper surface of the opto-electric hybrid unit, a recess positioning interconnect line is formed along the recess, the recess positioning interconnect line is made of a same material as the electrical interconnect lines and is formed on a same layer as the electrical interconnect lines,
• wherein the optical element unit and the opto-electric hybrid unit are coupled together, with the protrusion of the optical element unit and the recess of the opto-electric hybrid unit in fitting engagement with each other, whereby the optical element and the core for an optical path are aligned with each other so as to be capable of light propagation,
• wherein the electrical interconnect line of the connector body is embedded from the bottom thereof through an interior of the side wall thereof to the ceiling thereof, and
• wherein the board is electrically connected with the opto-electric hybrid unit through the electrical interconnect line of the connector body.
