Abstract
When forming an inductance device comprising internal conductors (,) which forms a coil and a close looped internal conductor (,) which surrounds the central shaft of the coil, a fixed frequency in a frequency band in which an inductive reactance occurs is set to a targeted frequency f, and values of a series resistance ingredient r and inductance L of the close looped internal conductor (,) are set to a value in a range which is prescribed in (2&pgr;f/3.15≦r/L≦2&pgr;f/0.32). Accordingly, the effect of the close looped conductive member (,) is obtained at an intended frequency, and a inductance device having a close looped conductive member (,) unlimited its shape and size can be obtained.
