Abstract
A magnetic element capable of obtaining a desired characteristic and at the same time having high productivity that enables cost reduction is provided. The magnetic element includes a first coil () to which a signal is inputted, a second coil () to which the signal inputted to the first coil () is transmitted, and includes a first core () having a first columnar leg portion () on which the first coil () is wound and a first peripheral wall portion () arranged on the periphery of the first columnar leg portion (), and a second core () having a second columnar leg portion () on which the second coil () is wound and a second peripheral wall portion () arranged on the periphery of the second columnar leg portion (). The relative permeability of the first core () is set higher than the relative permeability of the second core (), the first columnar leg portion () and the second columnar leg portion () abut on each other, and the first peripheral wall portion () and the second peripheral wall portion () abut on each other.
