Abstract
An LC component includes a coil conductor spirally wound around the outer peripheral surface of a wound core member having a substantially rectangular cross-section. A dielectric layer is arranged so as to cover the coil conductor. A capacitor electrode is provided on the dielectric layer so as to wind approximately once around the wound core member in the peripheral direction of the wound core member. The capacitor electrode includes first, second, third, and fourth surfaces. The capacitor electrode is divided by two cut grooves. One cut groove crosses the capacitor electrode obliquely from one side of the first surface of the capacitor electrode to the other side of the second surface adjacent to the first surface. Similarly, the other cut groove crosses the capacitor electrode obliquely from one side of the third surface of the capacitor electrode to the other side of the fourth surface adjacent to the third surface.
