Abstract: An aspect of the present invention is an optical modulator including an electro-optic substrate, an optical waveguide, and a signal electrode for applying an electric field corresponding to a modulation signal to the optical waveguide. The electro-optic substrate includes a trench portion, which is formed by digging a surface of the electro-optic substrate, and a ridge portion, which is formed in a ridge shape by the trench portion so that an optical waveguide is provided. The trench portion includes a first trench portion, which is a trench portion between a pair of branched optical waveguides, and a second trench portion, which is a trench portion other than the first trench portion. Digging depths of the first and second trench portions are different.
