Abstract
Provided is a magnetic core containing metal magnetic particles. A total area ratio occupied by the metal magnetic particles on a cross-section of the magnetic core is 75% or more. The metal magnetic particles include first large particles having an amorphous structure and having a Heywood diameter of 3 μm or more on the cross-section of the magnetic core, and second large particles having a nanocrystal structure and having a Heywood diameter of 3 μm or more on the cross-section of the magnetic core. An insulation coating of the first large particles is thicker than an insulation coating of the second large particles.
