摘要：
An optical waveguide device has an optical waveguide substrate and a supporting substrate. The optical waveguide substrate has a main body made of an electro-optic material and having a first main face and a second main face, an optical waveguide formed in or on the main body and an electrode formed on the side of the first main face of the main body. The supporting substrate is joined with the second main face of the main body. A low dielectric portion with a dielectric constant lower than that of the electro-optic material is formed in the supporting substrate.
