摘要： An electronic component includes a spiral or substantially spiral first inductor extending along a stacking direction while turning around a ring-shaped or substantially ring-shaped path. The first inductor includes first inductor conductors and a first interlayer connecting conductor connected to each other. The first interlayer connecting conductor passes through some insulating layers. A second interlayer connecting conductor passes through some insulating layers, and is connected in series and is located within the ring-shaped path. A first capacitor conductor is disposed closer to one side of the stacking direction than the first inductor is. The first capacitor conductor is at least partially superposed on the ring-shaped path to define a first capacitor between the first capacitor conductor and the first inductor, and is superposed on a portion of a region surrounded by the ring-shaped path to be connected to the second interlayer connecting conductor.
