PROBLEM TO BE SOLVED: To achieve a high frequency choke coil having wide band characteristics, easy to be manufactured and mounted.SOLUTION: The high frequency choke coil includes: a substrate 21; a coil body 25 formed with a pattern of a plurality of rounds in a spiral shape with a conductor on one surface side 21a of the substrate 21; and resistor 30, 40 formed with such a pattern as to connect conductors of different rounds of the coil body 25, for suppressing resonance caused by inter-wiring capacitance and floating capacitance between the conductors. Furthermore, a leg part 22 for substrate installation is projected on a lower surface side 21b of the substrate 21 to reduce the floating capacitance between the coil body 25 and an installation surface.SELECTED DRAWING: Figure 1 |
