Abstract
In a method of forming an assembly of an optical waveguide substrate and an optical fiber aligning substrate by adjoining an end face of a main body of the optical waveguide substrate and an end face of a main body of the optical fiber aligning substrate, a starting block formed by a flat rectangular plate is divided along a dividing surface which intersects perpendicularly to a side wall as well as a bottom wall of the starting block which are selected as a reference surface to obtain the main bodies of the optical waveguide substrate and optical fiber aligning substrate, optical waveguides are formed on the main body of the optical waveguide substrate by using the side wall and bottom wall as a positional reference, V-shaped guide grooves are formed in the main body of the optical fiber aligning substrate by using the side wall and bottom wall as a positional reference, and optical fibers are inserted into the guide grooves.
