ELECTRONIC COMPONENT

摘要

An electronic component has a shaft, a flange formed at an end of the shaft and constituting a core together with the shaft, a coiled conductor wound around the shaft, and an electrode terminal formed on the flange and connected electrically to an end of the conductor; wherein the shaft and flange are made of metal magnetic grains containing Fe which are bonded to each other by bonding of oxide film formed on each metal magnetic grain, and the shaft is more densely filled with the metal magnetic material than is the flange. The electronic component can achieve size reduction and frequency increase by improving the magnetic permeability while also improving the plating property for the terminal electrode.
