Abstract

Disclosed is a powder which includes metal particles, apatite layers covering the metal particles, and silica fine particles adhered to the metal particles or the apatite layers. This powder enables annealing at high temperatures without causing fracture of an insulating layer during production of a dust core. Consequently, a dust core having sufficiently high permeability while maintaining insulating properties of the insulating layer can be obtained by using this powder.
