The optical modulator includes a substrate 1, an optical waveguide including a Mach-Zehnder type optical waveguide formed in the substrate, and a modulation electrode (not illustrated) for modulating light waves that propagate through the optical waveguide, alight receiving element 5 is disposed to bridge over an output waveguide 24 configuring the Mach-Zehnder type optical waveguide so as to receive two radiated lights being radiated from a combining part in the Mach-Zehnder type optical waveguide, and, in the light receiving element, two or more light receiving areas (51 and 52) are formed apart from each other on a substrate of light receiving element 55.
