Abstract
An optical element-including opto-electric hybrid board includes an opto-electric hybrid board including an optical waveguide and an electric circuit board in order toward one side in a thickness direction, an optical element mounted on the electric circuit board at one side in the thickness direction of the opto-electric hybrid board, and a bonding member interposed between the optical element and the electric circuit board so as to bond the optical element to the electric circuit board. A thermal expansion coefficient of the bonding member is 80 ppm or less.
