LAMINATE OF MAGNETIC BASE MATERIAL AND METHOD FOR PRODUCTION THEREOF

摘要

[PROBLEMS] With respect to a laminate of a magnetic base material composed of a magnetic thin metal sheet and a polymer, to provide a laminate of a magnetic base material having an enhanced coefficient of thermal conductivity, since a conventional such laminate has a low coefficient of thermal conductivity and thus exhibits poor heat releasing property when the dissipation of the heat due to iron loss is intended. [MEANS FOR SOLVING PROBLEMS] Use is made of a laminate of a magnetic base material composed of a polymer layer and a magnetic thin metal sheet, characterized in that it has a coefficient of the volume resistance defined in JIS H 0505 in the direction perpendicular to the surface of the polymer layer of the laminate of less than 10<8> ohmcm. Said laminate can provide, when it is pressed, electroconductive points between the magnetic thin metal sheets, through the ejection of the polymer in the laminate to the outside thereof.
