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, a pair of end plates and each end plate are connected. The resonant frequency of the parallel resonant circuit is determined by the inductance and stray capacitance of the coils.The resonant frequency of the parallel resonant circuit is determined by the inductance and stray capacitance of the coils. is set to be approximately equal to the frequency of the high frequency signal.
