摘要：
In a multiple optical waveguide device, a transparent plate is bonded or joined on the top surface of a clad with which optical circuits and quartz glass substrates are covered, and optical reflection film is provided on the fringing area or the whole area of a joint surface of the transparent plate with the clad. Optical circuits or waveguide patterns can be recognized easily by visual inspection.
