Abstract
An inventive opto-electric hybrid board includes: opto-electric module portions respectively provided on opposite end portions of an elongated insulation layer and including a first electric wiring of a first electrically conductive pattern and an optical element provided on a front surface of the insulation layer; and an interconnection portion provided on a portion of the insulation layer extending from the opto-electric module portions, and including an elongated optical waveguide on a back surface of the insulation layer optically coupled with the optical elements, and having a light signal transmission core. Further, an electrically conductive dummy pattern is provided on the front surface of the insulation layer in the interconnection portion for reinforcing the interconnection portion. The electrically conductive dummy pattern reinforces the interconnection portion to protect the waveguide from bending and twisting, while ensuring the flexibility of the interconnection portion. This suppresses increase in light transmission loss.
