Inductor patterns (21a, 21b; 22a, 22b) are electrically connected to each other through long via-holes (28) formed in sheets, so that tubular structures (21, 22) each having an insulator filled therein and having a rectangular cross section are formed, respectively. The tubular structures (21, 22) are laminated through sheets to form an inductor (L1) having a double structure. A capacitor pattern (23) is opposed to the open ends of the inductor patterns, respectively, to form a capacitor (C1). That is, the capacitor pattern (23) is arranged between the tubular structures (21, 22). The capacitor (Cl) and the inductor (L1) having the double structure form an LC parallel resonance circuit. <IMAGE> |
