Zusammenfassung:: Iron core material 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 ?.mu..OMEGA. -cm, is preferred to have a value of the resistivity which may satisfy the following equation: < IMG >
