Abstract
Provided is a magnetic material including a plurality of flat particles containing a magnetic metal, and a matrix phase disposed around the flat particles and having higher electrical resistance than the flat particles. In a cross-section of the magnetic material, the aspect ratio of the flat particles is 10 or higher. If the major axis of one of the flat particles is designated as L and the length of a straight line connecting two endpoints of the flat particle is designated as W, the proportion of the area surrounded by the outer peripheries of parts in which flat particles satisfying the relationship: W ≤0.95×L are continuously laminated, is 10% or more of the cross-section.
