The invention provides an optical modulator module by which a dip appearing in a frequency characteristic of a microwave from a DC component to a high-frequency component can be reduced while maintaining the mechanical strength and facilitating handling of a substrate and besides securing the long-term reliability without processing the substrate itself. The optical modulator module includes a substrate, an optical modulator including an optical waveguide, a signal electrode, and a ground electrode, and a housing in and to which the optical modulator is accommodated and secured. The shape of a longitudinal section of the other portion of the optical modulator module than the substrate is asymmetrical with respect to a perpendicular line with which the portion of the signal electrode which extends in parallel to the optical waveguide is bisected in the longitudinal direction. The optical modulator module is applied typically to an optical communication system.
