PROTECTION ELEMENT, BATTERY CONTROL DEVICE, AND BATTERY PACK

WIPO Patent Application WO/2011/126091

A1

In order to efficiently transfer heat from a heating resistor to a low-melting-point metal body through a heat transfer path, disclosed is a protection element connected onto an electric current path of an electric circuit. Said protection element comprises an insulating substrate (60), a heating resistor (64) which is formed on one surface of the insulating substrate (60) with a first insulating layer (62) interposed therebetween, a low-melting-point metal body (67) which is disposed above the heating resistor (64) with a second insulating layer (65) interposed therebetween and constitutes part of the electric current path, and connection portions (611, 612) which are connected to both ends of the low-melting-point metal body (67) and electrically connect the electric current path and the low-melting-point metal body (67). The connection portions (611, 612) are provided on said surface of the insulating substrate (60) with a first glass layer (70) interposed therebetween.
