Abstract
In order to provide an optical modulator capable of preventing damage to the substrate and preventing deterioration of the properties of the modulator by reducing the stress on the substrate generated by the modulation electrode, there is provided an optical modulator, including: a substratehaving an electro-optic effect; an optical waveguideformed on the substrate; and a modulation electrode (signal electrode S and ground electrode G) provided on the substrateand modulating a light wave propagating in the optical waveguide, wherein a resinto reduce the stress on the substrategenerated by the modulation electrode is arranged between a part of the bottom surface of the modulation electrode and the substratefacing a part of the bottom surface of the modulation electrode.
