Abstract
An optical modulator includes a relay substrate having signal conductor patterns that connect input signal terminals and signal electrodes of an optical modulation element and ground conductor patterns, and a housing that accommodates the optical modulation element and the relay substrate. Regarding at least one signal conductor pattern, the two ground conductor patterns sandwiching the signal conductor pattern are formed in an asymmetrical shape in a plan view in a rectangular connection area including a signal connection portion at which the signal conductor pattern and the input signal terminal are connected. The connection area is centered on the at least one signal conductor pattern in a width direction, and has a width equal to a distance to the nearest adjacent signal conductor pattern and a height equal to a distance from an end of the signal connection portion farthest from a signal input side to the signal input side.
