Abstract

Die vorliegende Erfindung betrifft ein Laminat magnetischer Substrate mit einer hohen thermischen Konduktivität, um einen Zerfall der Wärmefreisetzungseigenschaften zu verhindern, der durch eine niedrige thermische Konduktivität ausgelöst wird, wenn exotherme Wärme aufgrund des Kernverlusts des Laminats magnetischer Substrate, umfassend eine dünne Magnetmetallplatte und eine hochmolekulare Verbindung, nach aussen freigesetzt wird.Das Laminat magnetischer Substrate, umfassend eine hochmolekulare Verbindungsschicht und eine dünne Magnetmetallplatte, wird verwendet, wobei der spezifische Volumenwiderstand wie definiert in der JIS H0505 zu einer Richtung senkrecht zur hochmolekularen Verbindungsschichtoberfläche des Laminats weniger als 10<SUP>8</SUP> Ocm beträgt. Das Laminat ist mit einem elektrischen Kontinuitätspunkt versehen, erzeugt zwischen den dünnen Magnetmetallplatten, so dass die hochmolekulare Verbindung innerhalb des Laminats zu der Aussenseite des Laminats durch Druckanlegen auf das Laminat gedrückt wird.
