Abstract: A transmission line has a signal electrode formed on one surface of a flexible printed circuit, and a ground electrode formed on the other surface of the flexible printed circuit. A connection terminal has signal terminals formed on both the surfaces of the flexible printed circuit and electrically connected to each other through a via hole, and ground terminals formed on both the surfaces of the flexible printed circuit and electrically connected to each other through the via hole. The signal terminal on the surface, on which the ground electrode is formed, is formed such that at least a width in an end portion on the transmission line side is narrower than a width of a part of the signal terminal on the surface, on which the signal electrode is formed, to be at the same position when the flexible printed circuit is seen in a plan view.

Abstract: To perform a stable bias control by improving detection accuracy of intensity of an dither signal component, which is detected by a photo detector, in an optical modulator including a bias electrode to which a dither signal is applied, and a photo detector that monitors an optical signal propagating through the inside of an optical waveguide in the same substrate. The optical modulator includes: a substrate having a piezoelectric effect (102); an optical waveguide (116a or the like) that is formed on the substrate; a bias electrode (158a or the like) that controls an optical wave that propagates through the optical waveguide; and a photo detector (168a or the like) that is formed on the substrate, and monitors an optical signal that propagates along the optical waveguide. At least one suppressing unit (190 or the like), which suppresses a surface acoustic wave that propagates from the bias electrode to the photo detector, is disposed between a region in which the bias electrode is formed and a portion in which the photo detector is disposed on the substrate.
