Abstract
An optical modulator using an optical modulation element in which an optical waveguide and a plurality of electrodes for controlling light waves propagating through the optical waveguide are formed on a substrate, in which at least one stress relieving structure is provided on an upper surface of the electrode opposite to a surface of the substrate in order to relieve stress generated due to pressure applied at the time of wire-bonding of a metal wire.
