Abstract: An electronic component includes: a first inductor; a second inductor connected in parallel with the first inductor; and a stack for integrating the first inductor and the second inductor, the stack including a plurality of dielectric layers stacked together. Each of the first inductor and the second inductor is wound about an axis extending in a direction orthogonal to a stacking direction of the plurality of dielectric layers. The number of windings of the first inductor and the number of windings of the second inductor are different from each other.

Abstract: An electronic component includes a stack including a plurality of first conductors and a plurality of second conductors. The plurality of first conductors include a first conductor group. The plurality of second conductors include a second conductor group arranged in a region adjacent to a region where the first conductor group is arranged. The plurality of first conductors further include a third conductor group arranged in a region adjacent to the region where the second conductor group is arranged and located to sandwich, with the region where the first conductor group is arranged, the region where the second conductor group is arranged. The first conductor group constitutes a plurality of parallel resonant circuits. The second conductor group constitutes a serial resonant circuit. The third conductor group constitutes another parallel resonant circuit.
