Abstract
An absorptive circuit element includes a core body made of non-conductive material, an inner conductor formed by winding a conductive wire around the core body with a gap provided between adjacent turns, a magnetic material surrounding outside of the inner conductor, the magnetic material being made of composite material containing ferromagnetic fine metal powder and insulating resin, a dielectric surrounding outside of the magnetic material, and an outer conductor formed on a surface of the dielectric.
