Insulating material-coated soft magnetic powder, dust core, magnetic element, electronic device, and moving body

An insulating material-coated soft magnetic powder including a plurality of individual particles, each individual particle comprising:

• a core particle that includes a base portion containing a soft magnetic material containing Fe as a main component and at least one of Si, Cr, and Al, and that includes an oxide film provided on a surface of the base portion and containing an oxide of at least one of Si, Cr, and Al;
• and
• an insulating film that is provided on a surface of the core particle and that contains a ceramic,
• wherein a thickness of the insulating film is 5 nm or more and 300 nm or less as measured from an interface between the insulating film and the oxide film using a scanning transmission electron microscope where an integrated state of the oxide film and the insulating film are confirmed,
• the oxide contained in the oxide film and the ceramic contained in the insulating film are mutually diffused at the interface between the oxide film and the insulating film,
• the insulating film is formed from melted or sintered insulating particles that collectively define a layer that surrounds the oxide film, and
• a majority of the insulating film is occupied by the insulating particles in a melted or sintered state that do not retain a particle shape rather than by insulating particles in the form of a particle that are not melted or sintered.
