Opto-electric hybrid board and manufacturing method therefor

An opto-electric hybrid board, comprising:

• an optical waveguide unit;
• and
• an electric circuit unit having an optical element mounted thereon, the electric circuit unit being coupled to the optical waveguide unit,
• wherein the optical waveguide unit comprises:
• an undercladding layer;
• a core for an optical path, the core being formed on a surface of the undercladding layer;
• an overcladding layer which covers the core;
• and
• a fitting hole for locating the electric circuit unit, the fitting hole being formed in a surface of the overcladding layer;
• wherein the electric circuit unit comprises:
• an electric circuit board;
• the optical element mounted at a predetermined portion on the electric circuit board;
• and
• a protruding portion which fits into the fitting hole;
• wherein the fitting hole of the optical waveguide unit is located and formed at a predetermined location with respect to an end surface of the core;
• wherein the protruding portion of the electric circuit unit is located and formed at a predetermined location with respect to the optical element;
• and
• wherein the optical waveguide unit and the electric circuit unit are coupled to each other in a state in which the protruding portion of the electric circuit unit fits into the fitting hole of the optical waveguide unit.
