It becomes possible to supply a high-frequency control signal to an electro-optic effect element in an optical module through an external RF cable. 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 the signal electrode and the ground electrode of the element and a coplanar line for connecting the center conductor of the connector with the outer conductor respectively formed 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.
