| 发明名称 | Coil component | ||
| 摘要 | A coil component is of the type where a helical coil is directly contacting a magnetic body where such coil component still meets the demand for electrical current amplification. The coil component is structured in such a way that a helical coil is covered with a magnetic body. The magnetic body is mainly constituted by magnetic alloy grains and does not contain glass component, and each of the magnetic alloy grains has an oxide film of the grain on its surface. | ||

| 主权项 | 1. A coil component of the type where a helical coil covered with a magnetic body is directly contacting the magnetic body, said coil component characterized in that the magnetic body is mainly constituted by magnetic alloy grains, other than ferrite grains, and does not contain a glass component, wherein the magnetic alloy grains consist of grains made of a magnetic alloy and an oxide of the magnetic alloy, said oxide being film covering the surface of the grains, said magnetic alloy grains being bonded together by the oxide film without any other binder and by metal-to-metal bonding of the grains made of the magnetic alloy where no oxide film is formed. | ||
