Abstract
An opto-electric hybrid board includes: an electric circuit board including an insulative layer, and an element mounting electrode formed on the front surface of the insulative layer; an optical element mounted on the element mounting electrode by contact frictional heat; and an optical waveguide including a first cladding layer in contact with the back surface of the insulative layer of the electric circuit board. Between the insulative layer and the first cladding layer, a reinforcing layer is provided at the portion corresponding to the element mounting electrode. A reinforcing layer is provided at the portion corresponding to the element mounting electrode, in the surface of the first cladding layer, which is on the side opposite to the insulative layer. The resin-made reinforcing layer is greater than the first cladding layer in storage modulus at the temperature of the board when the element is being mounted.
