Abstract
A soft magnetic material includes a plurality of composite magnetic particles () each including a metal magnetic particle () and an insulation coating () covering the surface of the metal magnetic particle (), wherein the insulation coating () contains Si (silicon), and 80% or more of Si contained in the insulation coating constitutes a silsesquioxane skeleton. Therefore, it is possible to effectively decrease a hysteresis loss while suppressing an increase in eddy-current loss.
