Abstract
The optical module has an element mounted thereupon for shifting an optical phase by the electro-optic effect, and includes an element for shifting an optical phase by an electro-optic effect having a signal electrode and a ground electrode formed thereupon; a connector for supplying a control signal of a microwave region to the signal electrode of the element, having a center conductor and an outer conductor; and a repeating board formed on a dielectric wafer having a coplanar line connecting the signal electrode and the ground electrode with the center conductor and the outer conductor of the connector respectively on the dielectric wafer, wherein an air layer is formed on the lower portion of the repeating board on which the center conductor of the connector is disposed.
