Abstract
A plurality of cylindrical inner conductor portions having different diameters are connected with each other to form an inner conductor. The inner conductor portions include high-impedance portions and low-impedance portions. The inner conductor is formed within an outer conductor with a nonuniform inner diameter. The inner conductor is formed so that the axial length of some of the inner conductor portions forming the high-impedance portions is smaller than the axial length of the other inner conductor portions forming the high-impedance portions, and the diameter of the inner conductor portions forming the high-impedance portions is greater than a predetermined minimum diameter.
