Abstract A spiral LC composite member is formed by splicing together a desired number of rectangular dielectric chips between two spiral coils with rectangular cross sections. A noise-cut filter circuit is formed by laminating and connecting a desired number of spiral LC composite members. A desired number of noise-cut filter circuits are layered through insulation sheets, and are enclosed by a magnetic body so that a magnetic circuit can be formed at the core and the outer circumference of the multi-layered body. This constructs a filter circuit serving as a reactor and a capacitor.
