Abstract

Die vorliegende Erfindung betrifft ein Wärmeerzeugendes Element einer elektrischen Heizvorrichtung, insbesondere für ein Kraftfahrzeug, mit einem PTC-Element, beidseitig daran anliegenden Leiterbahnen und einer elektrischen Isolation, die außenseitig auf die Leiterbahnen aufgebracht ist, die dadurch verbessert ist, dass zumindest eine der Leiterbahnen durch ein mit Durchbrechungen (14) versehenes elektrisch leitendes Element (1) gebildet ist, das in Höhenrichtung der Leiterbahn diskrete Stützstellen aufweist, die an dem PTC-Element (4) und/oder der elektrischen Isolation (8) anliegen, wobei Freiräume innerhalb der Leiterbahn durch eine adhäsiven Masse (12) ausgefüllt sind.
