Abstract:
An inductor component includes an air core coil in which an air core inductor wire is provided in an air core body containing a non-magnetic material, and a magnetic core coil in which a magnetic core inductor wire is provided in a magnetic core body containing a magnetic material. The air core body and the magnetic core body are combined or integrated. A magnetic material content in a peripheral region around the air core inductor wire is lower than 50%. The magnetic material content in a peripheral region around the magnetic core inductor wire is higher than or equal to 50%.
