ABSTRACT:
An optical waveguide device1A has a substrate22and a supporting body10for supporting the substrate. The substrate22has a main body2made of an electrooptic material and one and the other main faces, optical waveguides3a,3band electrodes4B,4C provided on the side of the one main face2aof the main body2The supporting body10is joined with the substrate2on the side of the other main face, and the electrode has a feedthrough portion. The device1A further has a low dielectric portion7provided under the feed through portion and between the other main face2bof the main body2and the supporting body10.
