Abstract: A magnetic powder includes an insulating layer formed of a polymer material which is directly coated on a powder particle core having magnetic properties. An inductor containing the same is also provided. The magnetic powder does not include a separate inorganic insulating layer between the powder particle core and the insulating layer, the insulating layer has a relatively uniform thickness, and a body formed using the magnetic powder does not contain a separate binder or curing agent, such that a high permeability and an excellent Q factor may be implemented.
