摘要： A first winding of a choke coil is closely wound in a single layer on the outer periphery of a substantially cylindrical body portion of a first bobbin. A second winding is closely wound in a single layer over the first winding. A third winding is closely wound in a single layer on the outer periphery of a substantially cylindrical body portion of a second bobbin. A fourth winding is closely wound in a single layer over the third winding. The first, second, third and fourth windings are wound so as to mutually strengthen magnetic fluxes when an in-phase noise current flows. The first and second windings are connected to a pair of signal lines via which differential transmission communication is performed and on which a power supply current is sent out. The third and fourth windings are connected to a pair of signal lines via which differential transmission communication is performed and on which the power supply current returns. Thus, a circuit including a compact choke coil having large inductance and better high-frequency characteristics, and the choke coil is provided.
