るラインフイルタ。[Claim for Utility Model Registration] In a line filter that is interposed in a power supply line that supplies power to an electronic circuit and prevents high-frequency signals from the electronic circuit from propagating to the power supply side, the outer periphery of the winding tube through which the core is inserted. A plurality of fitting grooves are formed at intervals in the axial direction of the winding tube, a roughly C-shaped partition plate is fitted into each fitting groove, and a conductive wire is wound between each partition plate. A line filter comprising a plurality of coils, and a parallel resonant circuit whose resonant frequency determined by the inductance and stray capacitance of the coils is set to be approximately equal to the frequency of the high frequency signal.
