A Mach-Zehnder waveguide type optical modulator is provided which includes a thin plate 1 with a thickness of 20 μm or less formed of a material having an electro-optical effect, an optical waveguide 2 formed on a front surface or a rear surface of the thin plate, and a modulation electrode modulating light passing through the optical waveguide. The optical waveguide includes an input optical waveguide 21, branched optical waveguides 23 to 28, and an output optical waveguide 30. The branched optical waveguide includes an input branching portion (region B) in which the input optical waveguide is branched into a plurality of optical waveguides, an output merging portion (region D) in which the plurality of optical waveguides connected to the output optical waveguide are merged, and a parallel portion (region C) formed between the input branching portion and the output merging portion. At least one of the input branching portion and the output merging portion has a ratio l/d of a length l along a symmetry axis of the branched optical waveguides to a gap d of the optical waveguide in the parallel portion in the range of 33 to 100.
