Abstract
An optical modulator includes a plurality of Mach-Zehnder optical modulation units. Each of the plurality of Mach-Zehnder optical modulation units include a pair of first signal wirings, a pair of first ground wirings, a pair of first signal electrode pads, and a pair of first ground electrode pads. The pair of first ground electrode pads is displaced by less than the first interval from the pair of first signal electrode pads so as to separate from a center line of each of the plurality of Mach-Zehnder optical modulation units.
