Abstract
An optical modulator module includes: a substrate in which a plurality of optical modulators are formed; a connector configured to include a plurality of terminals to which a plurality of signals for driving the plurality of optical modulators are input; and a relay board provided between the substrate and the connector. Each of the optical modulators includes an optical waveguide, a modulation electrode formed near the optical waveguide, and a feeder electrode electrically connected to one end of the modulation electrode. The terminals are arranged in parallel to a longitudinal direction of the substrate. Positions of respective ends of the modulation electrodes at which the respective feeder electrodes are electrically connected are the same as positions at which the respective terminals are provided in the longitudinal direction. Wiring patterns are formed on the relay board so as to electrically connect the terminals to the respective feeder electrodes.
