Abstract: An optical modulator includes a substrate, an optical waveguide, a control electrode applying a high frequency signal in order to modulate light waves propagating through the optical waveguide, and a relay substrate provided with a relay line to transfer the high frequency signal to the control electrode. The control electrode and the relay line together have a coplanar line structure inclusive of at least electrical connection portions of both the control electrode and the relay line. The control electrode includes an electrical connection portion and a routing portion positioned between the electrical connection portion and an active portion applying an electrical field to the optical waveguide. The routing portion has a coplanar line structure. A distance between ground electrodes sandwiching a signal electrode in the electrical connection portion of the control electrode is substantially equal to a distance between ground electrodes sandwiching a signal electrode of the routing portion.
