PROBLEM TO BE SOLVED: To provide a method of manufacturing a soft magnetic core superior in soft magnetic properties and capable of preventing deposition of an Fe compound.SOLUTION: The method of manufacturing a soft magnetic core includes the steps of: forming a layer of an endothermic reaction material 3 the endothermic reaction temperature of which is in a range of a first crystallization temperature and a second crystallization temperature of an amorphous alloy thin band 2 on at least one surface of the amorphous alloy thin band 2; and heat-treating a core formed with an amorphous alloy thin band 2 in which a layer of the endothermic reaction material 3 is laminated; to thereby produce a soft magnetic core 1. |
