    Abstract: Provided is an optical waveguide element capable of connection such as wire bonding, suppressing usage of gold, and suppressing deterioration of a conductor loss. An optical waveguide element includes a substrate 1 having an electro-optic effect, an optical waveguide 2 formed on the substrate, and a control electrode (30, 31) provided on the substrate and controlling a light wave propagating through the optical waveguide. The control electrode is made of a material other than gold, and the gold is disposed on at least a wire bonding portion 4 of the control electrode.
