摘要: Disclosed is an iron core material, comprising a high density compression molded product of a mixture of magnetic powder of iron or iron alloy having a mean particle size of 100.mu. or less and an insulating caking material such as thermosetting resins. The magnetic powder, when its mean particle size is represented by D.mu. and its resistivity by .rho..mu..OMEGA. -cm, is preferred to have a value of the resistivity which may satisfy the following equation: ##EQU1##
