Abstract

In an optical waveguide device, in a cross direction intersecting an extension direction of waveguide sections, one or more bridge portions of a ground electrode closer to a center of stress distribution of a stress due to a support member, and one or more bridge portions of a ground electrode farther from the center of stress distribution are formed with different shapes. The structure of the ground electrodes is devised so that a stress negating the difference in stress characteristics between the plurality of waveguide sections, generated by the stress applied from the support member to a substrate, is applied from the ground electrode to the substrate.
