The insulating material comprises a phenol resin and/or a silicone resin, and the lubricant comprises at least one compound selected from the group consisting of magnesium stearate, calcium stearate, strontium stearate, and barium stearate. It is possible to achieve a dust core having high saturation magnetic flux density, low losses, and satisfactory permeability with its dependence on frequency being improved.
