Abstract
Modulation electrodes, bias electrodes, and bias electrodes are disposed in this order in a light wave-travelling direction in an optical modulation region modulating light having a wavelength. On the other hand, in an optical modulation region modulating light having a wavelength, the bias electrodes, the bias electrodes, and the modulation electrodes are disposed in this order in the light wave-travelling direction. That is, an order of the modulation electrodes and the bias electrodes in a longitudinal direction of a substrate is changed for each of the wavelengths.
