摘要： The present invention is directed to provide a light modulation device capable of not only restricting the faint light propagating in the adhesive layer from being re-incident on the thin substrate but also increasing an adhesive strength of the thin substrate and the supplementing plate. The invention is characterized in a light modulation device having a thin substrate 1 made of material with an electro-optical effect and with a thickness of below 20 μm; an optical waveguide 2 formed on a surface of the thin substrate or the other surface thereof; and a modulation electrode 3 formed on the surface of the thin substrate and for modulating light passing through the optical waveguide, comprising: a supplementing plate 5 adapted to be bonded to the thin substrate via an adhesive layer 4, wherein a bonding surface of the supplementing plate is formed as a rough surface 10 relative to a bonding surface of the thin substrate. A roughness of the rough surface is preferred to be over 1/10 of a wavelength of faint light propagating in the adhesive layer.
