摘要： The present invention has an object to provide a Mach-Zehnder optical modulator with the excellent productivity and reliability, which can obtain a favorable optical response characteristic even if a high frequency electric signal is applied to a signal electrode. To this end, the present optical modulator is configured such that, in a Mach-Zehnder optical modulator in which an optical waveguide and a coplanar electrode are formed on a surface of a substrate having an electro-optic effect, floating electrodes formed using a conducting material, are provided on side faces along parallel waveguides, among side faces substantially perpendicular to the surface of the substrate. Thus, even when a high frequency electric signal is applied to the signal electrode, a phenomenon is suppressed in which a particular frequency resonates within the substrate, and an occurrence of dip in a particular frequency is avoided.
