Abstract
A U-shaped groove and a V-shaped groove are formed onto a cladding disposed on a substrate, a core and a metal structure are formed inside the grooves, respectively, and then the substrate surface is planarized. Further, after a cladding is formed again, the substrate is cut and the cut surface is polished such that the metal structure inside the V-shaped groove has a predetermined thickness, thereby forming a scattering body.
