Abstract
This magnetic core (1) comprises: a columnar core part (11) that is arranged inside a coil (2); and a tubular yoke part (12) that is arranged outside the coil (2). The core part (11) and the yoke part (12) overlap the arrangement region of the coil (2) in the axial direction. The entirety of the core part (11) is configured from a high magnetic flux density material that has a higher magnetic flux density than commonly used magnetic materials.
