An optical modulator is provided with a substrate (1) having electro-optical effects; an optical waveguide (12) formed on the substrate (1) for guiding light waves; and an advancing wave electrode (4) which is formed on one side of the substrate (1) and composed of a center conductor (4a) for high frequency electric signal for applying a high frequency electric signal for modulating light, and a plurality of grounding conductors (4b, 4c). The optical waveguide (12) is provided with Mach-Zehnder light wave guide which is provides with a plurality of interacting optical waveguides (12a, 12b) for modulating phase of light by applying a high frequency electric signal to the traveling wave electrode (4). The center conductor (4a) and the grounding conductors (4b, 4c) are arranged so that the widths of the interacting optical waveguides (12a, 12b) are at least partially different from each other and an efficiency of the high frequency electric signal and that of interaction of light propagating in the mutual action optical waveguides (12a, 12b) are substantially equal.
