An optical modulator comprises an optical waveguide provided on an electro-optic substrate and formed of a first region for optical phase modulation and a second region for optical amplitude modulation cascaded with each other on the substrate, a signal electrode covering the optical waveguide for the first and second regions, and a ground electrode covering a surface of the substrate for the first and second regions, wherein the signal electrode includes an electrode strip extending on the surface of the substrate to continuously cover the optical waveguide from the first region to the second region, and wherein the ground electrode includes an electrode strip extending from the first region to the second region and covering the optical waveguide only in the first region.
