An optical waveguide device module has an optical waveguide device including an optical waveguide formed in a substrate, and a control electrode for controlling light; and a connection substrate including an interconnection, provided to the outside of the waveguide device, electrically connected to the control electrode. The control electrode includes ground electrodes that sandwich a signal electrode. The connection substrate has ground lines that sandwich a signal line. A width of the signal electrode in an input or output end is smaller than a width of the signal line on the waveguide device side. A distance between inner edges of the ground electrodes closest to the signal electrode, measured at an input or output end of the control electrode, is larger than a distance between inner edges of the ground lines closest to the signal line on the waveguide device side of the connection substrate.
