Abstract
An opto-electric hybrid board connector includes an opto-electric hybrid board extending along a transmission direction of light in an optical waveguide, and a connector to which an attached region of the opto-electric hybrid board is attached. The attached region has a board front end surface for inputting and outputting light to and from the optical waveguide. The connector has a connector front end surface disposed to be flush with the board front end surface. The surface roughness SRa1 of the board front end surface is 0.2 μm or more and 3 μm or less. A difference D between the surface roughness SRa1 of the board front end surface and the surface roughness SRa2 of the connector front end surface is 1 μm or less.
