This resonant circuit (1) is provided with a resonator (11). An inductor (Lp1) is connected in parallel to the resonator (11). An inductor (Ls1) is connected in series to the parallel circuit of the resonator (11) and the inductor (Lp1). In addition, a variable capacitor (Cp1) is connected in parallel to the series circuit of the inductor (Ls1) and the parallel circuit of the resonator (11) and the inductor (Lp1), and a variable capacitor (Cs1) is connected in series to these circuits. Consequently, there are provided a resonant circuit which is capable of coping with more communication signals, and a high frequency filter. |
