Abstract
An optical waveguide device 1A has a substrate 22 and a supporting body 10 for supporting the substrate. The substrate 22 has a main body 2 made of an electrooptic material and one and the other main faces, optical waveguides 3a, 3b and electrodes 4B, 4C provided on the side of the one main face 2a of the main body 2 The supporting body 10 is joined with the substrate 2 on the side of the other main face, and the electrode has a feedthrough portion. The device 1A further has a low dielectric portion 7 provided under the feed through portion and between the other main face 2b of the main body 2 and the supporting body 10.
