Abstract

On a substrate (1), a core layer (2) is formed such that the core layer (2) includes a rib section (2a) fabricated to be integral therewith. The core layer (2) and the rib section (2a) are formed with a liquid material to be solidified under an energy irradiation, for example, a UV-setting resin. A clad layer (3) is disposed on the core layer (2). A buffer layer (4) is formed between the core layer (2) and the substrate (1).
