An optical modulator includes a substrate having an electro-optic effect, an optical waveguide that is formed in the substrate, and a modulation electrode (not illustrated) for modulating a light wave that propagates through the optical waveguide. In the optical modulator, a light-receiving element is disposed on the substrate, and the light-receiving element includes a light-receiving section that receives a light wave that propagates through the optical waveguide, and the light-receiving section is located on the downstream side of a center of the light-receiving element in a light wave propagating direction.
