<p>Inductor patterns (24a, 24b) are electrically connected through long via-holes (23) formed in sheets (14, 15), respectively. The long via-holes are arranged along the right-, left-edges of the inductor patterns, respectively. The inductor patterns (24a, 24b) and the long via-holes (23) form an inductor (L1) having a tubular structure with a rectangular cross section and filled with an insulator therein. A capacitor pattern (25) is opposed to the open ends of the inductor patterns through the sheets, respectively, to form a capacitor (C1). That is, the capacitor pattern (25) is laminated inside of the tubular structure of the inductor. The capacitor and the inductor having the tubular structure form an LC parallel resonance circuit. <IMAGE></p> |
