PURPOSE:To put an LC filter into practical use by decreasing the size of a coil conductor fixed to one face of a dielectric base than the size of the coil conductor fixed to other face of the dielectric base. CONSTITUTION:An electrode 14, capacitor electrodes 9a, 10a are used as edges and a so-called T type high-pass filter having the same equivalent circuit as that of a conventional LC filter is constituted. The size of a coil conductor 11 of a print coil constituting part of the LC filter is decreased more than the size of the coil conductor 12, the stray capacitance Cp between the both is less regardless of the insertion of the dielectric base. Thus, the decrease in the self-resonance frequency f0 is less and a sufficiently practical frequency characteristic is obtained.
