ABSTRACT:
A coil package which makes it easy to handle a high-frequency cone/pyramid-shaped coil and enhance frequency characteristics without degrading the characteristics of the coil. The cone/pyramid-shaped coil has a conical or pyramidal shape formed by wiring a conductor wire around an outer peripheral surface of a core such that the winding diameter of the coil progressively decreases from one end to the other end of the coil. The coil and a dielectric substrate are integrated with each other by forming a hole for inserting a tip portion of the coil in the dielectric substrate, making the bottom of the hole and a back surface of the dielectric substrate electrically continuous by a via, placing the coil in the hole by directing a small-diameter side of the cone/pyramid-shaped coil to the hole, electrically connecting the bottom of the hole and a tip-side lead wire extending from the coil to each other, and connecting an electrode on a large-diameter side of the coil to an electrode on the dielectric substrate.
