Abstract
A method for connecting optical waveguides to optical fibers, the optical waveguides being arranged side by side in an optical waveguide circuit device, the method including inserting optical fibers into arranging guide grooves formed side by side in a guide substrate of an optical fiber array device, warping the optical fiber array device by a contraction stress caused by hardening of an adhesive for attaching the guide substrate to a cap plate for attachment and fixing, and optically connecting the optical waveguides to the optical fibers, by facing a connection terminal surface of the optical waveguide circuit device to a connection terminal surface of the optical fiber array device in the curved shape.
