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.
