A complex resonance circuit comprises one inductance element (1) and two capacitors (2, 3) connected to the inductance element (1). The inductance element (1) has one magnetic core (10), a winding (11) wound around the magnetic core (10), and two resonance windings (12, 13). Terminals (11a, 11b) are connected to both ends of the winding (11), respectively. Both ends of the resonance winding (12) are connected via a capacitor (2), and both ends of the resonance winding (13) via a capacitor (3). The magnetic core (10), the resonance winding (12), and the capacitor (2) constitute a first parallel resonance circuit. The magnetic core (10), the resonance winding (13), and the capacitor (3) constitute a second parallel resonance circuit. The complex resonance circuit has a complex resonance characteristic determined by combining of the resonance characteristics of the two parallel resonance circuits.
