To provide a manufacturing method of coating magnetic metal fine particles having particle sizes of nanometer order and attaining compatibility between long-term preservability in the atmosphere and chemical resistance in recycling, and to provide a manufacturing method of a magnetic component using the coating magnetic metal fine particles.

The manufacturing method of coating magnetic metal fine particles comprises: a process for forming magnetic metal fine particles 10 composed of magnetic metal; and a process of forming a non-magnetism coat 20 on a surface of the magnetic metal fine particles by using a dry process. The manufacturing method of a magnetic component includes a process of compression molding the coating magnetic metal fine particles.
