ABSTRACT:
A cladding layer7is formed on a base body made of a material for an optical waveguide, and a groove is formed in the base body and the cladding layer7. The base body and the cladding layer are joined to a supporting substrate with the cladding layer7positioned on the side of the supporting substrate1. The base body is machined and thinned to form a thin plate30so that the groove penetrates through the thin plate30. An end face14A on the groove12side of the optical waveguide13A is contacted with a light absorbing material or light reflecting material9to form a reflecting mirror.
