| 摘要 | Provided is an electronic component having a core that can achieve size reduction and frequency increase by improving the magnetic permeability further while also improving the plating property for the terminal electrode. 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 a metal magnetic material, and the shaft is more densely filled with the metal magnetic material than is the flange. | ||

| 主权项 | 1. An electronic component comprising: 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 coiled conductor; wherein the shaft and flange are made of a metal magnetic material, and the shaft is more densely filled with the metal magnetic material than the flange, wherein a/b, where a represents a fill ratio of metal magnetic material of the flange and b represents a fill ratio of metal magnetic material of the shaft, is 0.9 to 0.97. | ||
